Skin Peeling Inside The Mouth

Skin Peeling Inside The Mouth

Skin peeling inside the mouth is not something uncommon. Most people experience it. If this is your first time that the skin is peeling inside the mouth or inside of the lips, I will try to help you find the cause of that.

First of all, don’t worry. Usually, this kind of tissue sloughing happens for some minor reason and it goes away quickly.

What Are The Possible Causes Of Skin Peeling Inside The Mouth?

There are many reasons for this uncomfortable condition. We will go through the most frequent triggers. No matter what is the cause, try to keep your mouth clean, and drink a lot of water. Hydration will help you heal your mouth.


The most common reason is your toothpaste. Almost every toothpaste contains some aggressive ingredients that can be harmful to the skin inside your mouth or inside your lips. The most aggressive ingredient that can damage your skin barrier is SLS – sodium lauryl sulfate.

This ingredient can also be found in shampoos or detergents. It has an abrasive effect and it helps to create foam. An abrasive effect in toothpaste is needed to help remove the remains of the food and drinks. To put it simply, SLS is the main cleaning agent that makes your teeth clean and free of dirt.

Another positive effect of SLS is the fact that it helps the fluoride work better. As you can see, SLS seems like a good and strong ingredient in your toothpaste. However, many people are sensitive to this ingredient. Some people can’t stand the presence of SLS in soaps, detergents, or shampoos. Many of them are allergic to SLS.

The skin on the hands or scalp is thicker and less sensitive, but sometimes the strength of SLS can damage. So, you can imagine what this ingredient can do to the thin, sensitive skin inside your mouth.

Even if you’ve been using the same toothpaste for a long time, a negative reaction can happen. If you know that toothpaste is responsible for the skin peeling in the mouth, just stop using it. Find some mild toothpaste with natural and gentle ingredients.

Food And Drinks

Food and drinks are also known for causing trauma inside your mouth. Maybe the skin inside your mouth is peeling because you drank something very hot or cold.

Sometimes the damage can happen because some food is just too strong for your mouth. For example, pineapple is highly acidic, and it can cause irritation and damage inside your mouth or your lips.

Of course, it’s hard to know which food or drink is acidic or caustic and potentially damaging, but as soon as you notice the changes and irritation, it would be good to stop consuming it.

You could consume it but in moderation. Some foods and drinks will irritate everyone’s mouth if you eat too much of them. When it comes to food and drinks and skin peeling in the mouth, there is something more important than the above. And that is – allergies.

Some foods don’t contain any irritating ingredients, but they still damage the inside of your mouth. That means that you’re probably allergic to some foods. It’s possible to develop allergies to certain things even when you’re an adult, so take care of this.

Also, it doesn’t have to be some severe allergy. But, if you notice that something is damaging to your skin barrier inside the mouth, get yourself checked. As usual, avoid those foods and drinks.

I would like to mention that when it comes to food and drinks these are the most common allergies: eggs, nuts, cow’s milk and dairy products, seafood, gluten, soy, and fish.

Oral Trauma

If some kind of trauma happened inside your mouth, that could be the reason why the skin inside your mouth is peeling. It could be a burn, or maybe you’ve been brushing too hard.

Skin peeling inside the mouth can happen after a dentist’s appointment. The anesthesia, medications, or extraction can be damaging to the skin barrier and that’s when skin peeling begins.

This condition can also happen after teeth whitening, root canal procedure, and dental implants procedure.

Sometimes the abnormal growth or anatomy of your teeth can damage the skin inside the mouth. If that’s the case, you should see your dentist as soon as possible to get that tooth or teeth fixed. Finally, oral trauma can be caused by accidents, falls, or other injuries.

Biting Your Cheeks and Skin Inside the Mouth

To be fair, this is also an oral trauma. However, it is something quite common and it’s not marked as something serious. Some people bite their nails, some people tap with their feet, and some people bite their cheeks and skin inside the mouth.

This can cause damage which leads to skin peeling in the mouth. It can also cause scarring if it’s happening for a long time.

Sometimes people don’t do this on purpose. It happens that their teeth are positioned in a way that they are “catching” the skin, especially while they’re sleeping.

This is not something very dangerous, but it’s a habit that won’t do you any good. Besides, tissue sloughing is uncomfortable and often painful. If you bite the skin indie the mouth or lips too hard, it could get infected over time. Because of this, try to find another way to get rid of your anxiety.

Oral Thrush

Oral thrush is a yeast infection inside your mouth. It’s also called candidiasis. This fungal infection happens when the fungus Candida albicans grows inside your mouth. This fungus is normal in your body, but sometimes it multiplies and causes problems.

It doesn’t have to appear in your mouth, it can appear in other parts of your body. There are a few reasons why Candida grows: taking antibiotics, corticosteroids, or contraceptive pills, diabetes, infections, cancer, HIV, wrong-sized dentures, and smoking.

If the growth of Candida is causing an oral thrush, you will notice the skin peeling inside the mouth, lesions, smelly breath, and white buildup. If this is the case, you should see a doctor as soon as possible.

Some home remedies may help, but in this case, you will need medication and a special diet to overcome the growth of Candida albicans. Oral thrush can lead to some more serious conditions, so don’t neglect it and go see your doctor.

Steven-Johnson Syndrome – SJS

Steven-Johnson syndrome is a condition that affects the skin and mucosa. When someone is suffering from this disease, their skin is covered in rashes which lead to blisters and wounds. Higher body temperature and fever symptoms are also present.

After some time, skin peeling inside the mouth starts and after a few days of peeling, the skin starts to heal. This syndrome is often triggered by some medication and it can affect the skin and mucosa all over your body.

Oral Keratosis

Oral keratosis is the condition where skin inside your mouth and lips peels off easily. Everyday rubbing, chewing, or brushing teeth can cause the skin to peel.

This condition is not something that can’t be managed with proper care and hygiene. You just have to find something that works for you. Some people’s skin and mucosa are more prone to damage and irritation, and it’s important to take care of them.

Lichen Planus

Lichen Planus is a disease that causes irritation, selling, and redness. It can affect skin, nails, hair, and mucous membranes. Oral lichen planus can cause tissue sloughing and irritation in the mouth and throat. Oral mucosa is very sensitive.

How To Treat The Skin Peeling Inside the Mouth

If you know the cause of your problem, there is no need to go to the doctor’s office. If the problem is your toothpaste, change it. Use something less aggressive.

If the skin inside your mouth is peeling because you’ve burned it or damaged it with something, take care of your hygiene, drink plenty of fluids, and rinse with hydrogen peroxide or sage tea.

Another important thing that will help with this issue is taking some probiotic supplements. Eat softer food to avoid additional friction and rubbing of the damaged area. Your mouth and lips will heal in the next few days.

However, if the skin peeling inside the mouth is bothering you for a while, and it’s causing you problems, discomfort, and pain, you have to see a doctor. It may seem like a small thing, but it can be a sign of something more serious.

How To Prevent The Skin Peeling Inside the Mouth


When it comes to some serious conditions, there is nothing you can do except go to the doctor. However, if you’ve been experiencing skin peeling inside the mouth, it would be a good thing to change and upgrade your oral hygiene.

The most important thing to do is brush your teeth 2-3 times a day. Nowadays, brushing your teeth is more important because of the food and drinks we consume.

In the past, people’s diets didn’t include so many processed foods, sugars, additives, and artificial flavors. Unfortunately, we are surrounded by these things.

Eating and drinking can cause many things in our bodies, and it also affects our mouths. Toothpaste is also filled with too many ingredients that can be aggressive for our mouth, tongue, teeth, and gums.

Skin peeling in the mouth is just one of the possible problems. Because of that, you need to take care of your mouth.

Brushing your teeth regularly with a good toothbrush can do wonders. The brush with softer bristles is always a better choice since can’t damage the gums or the skin.

Of course, that doesn’t mean you can’t use a hard-bristle toothbrush. The best thing to do is to ask your dentist for a suggestion. I recommend looking into electric toothbrushes. They clean much better than the regular ones.

After choosing the right toothbrush, pick good toothpaste. Find some effective and gentle toothpaste. Even if your teeth are not that sensitive, pick a good toothpaste with good ingredients that won’t cause any irritation.

The most important step of your oral hygiene is to properly brush your teeth. There are tons of tutorials and videos online if you need some guidance. Don’t put too much pressure and brush your teeth for at least 3 minutes in every direction.

Use back-and-forth strokes, circular motions, and horizontal and vertical strokes. Don’t forget to clean your tongue. There are tongue scrapers available if you want to clean yours thoroughly.

Of course, last but not least, is flossing. Flossing will help you to clean the spaces between your teeth that are not reachable when brushing. There are also interdental toothbrushes available for those hard-to-reach places.

This is a basic instruction manual for oral hygiene. You can always add a good mouthwash or a mouth shower. There are so many options that can improve your dental routine.

Of course, don’t forget to check your oral health regularly. Make an appointment at the dentist as often as you can. Healthy teeth are not just important for good looks.

There are so many nerves and blood vessels in your teeth and like everything else in your body, your teeth are connected to your brain. Teeth problems can often be a sign of something more serious. Because of this, you have to take care of your teeth not just for your looks, but because of your health.

Oil Pulling For a Healthier Mouth and Teeth

Oil pulling became popular a few years. It’s a process in which you take a tablespoon of oil into your mouth and swirl it around for 15 minutes. After that, you spit it out.

You’re probably wondering why this is recommended. It is proven that oil pulling can strengthen teeth and gums. Oil traps bacteria and toxins, which makes your mouth cleaner and healthier.

It reduces inflammation and it can prevent cavities. In general, it makes your teeth stronger.

Many people have reported positive results with oil pulling. Some people say that it can whiten the teeth because it removes staining and plaque.

I would like to mention another benefit of oil pulling, and that is better health in general. Since oil traps toxins and bacteria, it prevents them from getting into your system further.

People usually use coconut oil, but you can use sesame oil, sunflower oil, avocado oil… Oil pulling can also be done if the skin inside your mouth is peeling. It will heal faster, and it will be less uncomfortable.

Foods For Good Oral Health

Oral hygiene is a priority for good oral health. However, it’s also important what kind of food you eat. A good diet will make your teeth stronger and more beautiful. Also, healthy food will boost your immune system and you will have fewer problems with your oral health.

If you eat healthy, there is a good chance you will avoid skin peeling in the mouth. So, if you’re not eating right and you have problems, it’s time to change that. I will suggest some good, nutritious food that will do you good.

Dairy Products

Cheese, yogurt, and milk are great for improving the quality of your teeth. Dairy products have a lot of calcium and protein, which are essential for strong teeth and protection from cavities.

Celery, Carrots, and Other Crunchy Vegetables

Crunchy vegetables like celery and carrots are great for your teeth. They have a lot of nutrients that are great for many things, but the fact that you have to chew them well before swallowing makes them useful as natural cleaners for your teeth.

When you have to chew a lot, the production of saliva in your mouth is increased. Saliva is good for your health, so this is another plus.

Green Vegetables

You’ve probably heard that green, leafy veggies are amazing for your health and body. They have so many great nutrients and they will help you to preserve good teeth.

Water With Fluoride

Water is the healthiest drink and enough water in our bodies is great for many things. Drinking water with added fluoride is great for fighting against bacteria and cavities.

It’s also helpful to drink it if you don’t want to have smelly breath. Drinking water is also great because it rinses down any residue on your teeth. Of course, you still have to brush your teeth, but drinking a lot of water will make it easier.

Pears and Apples

Apples and pears are great for your oral and digestive health. They have a lot of fiber and nutrients that will protect you from unwanted bacteria. Chewing apples and pears are helpful because they help to reduce inflammation in the mouth. They’re also great for your gums and fresh breath.


Strawberries are delicious, healthy, and soft. Eating strawberries I great because they contain natural acid that is good for cleaning your teeth. Some people use crushed strawberries to massage their teeth and gums. Also, many people can confirm that they can whiten your teeth with time.


Nuts like almonds, cashews, and peanuts are filled with vitamins, nutrients, minerals, and protein. Eating nuts will help you to have stronger bones and teeth. Of course, since they do have a higher level of fats, don’t eat a lot of them.

In addition to these great foods, it’s important to eat food packed with proteins, healthy fats, and carbs. If you make an effort to have a balanced diet, your teeth will thank you.

Foods That Are Not Good For Your Oral Health

Just like some foods can help you with your oral health, some foods can be damaging to your oral cavity.

 Carbonated Drinks

Drinking carbonated drinks is not good for any part of your body. Carbonated drinks can damage your tooth enamel because of the acid they contain.

Colored, carbonated drinks can severely stain your teeth. However, if you drink a soda once in a while, don’t brush your teeth right after drinking it, because it could be damaging to the teeth. Wait a while a drink some water in the meantime.


We all love candy, but we also know that it’s not good for us. Sour and sweet candy has a lot of sugar that sticks to your teeth and it’s hard to wash off. As you know, sugar is almost always responsible for bad teeth.

Starchy Food

Food that has a lot of starch is not good for your teeth. Starch starts to break down into sugar as soon as you start chewing. That way, the sugar gets trapped between your teeth, which is not good.

Dried Fruits

Dried fruits are sugary and their texture makes it easy for that sugar to stick to your teeth. Dried fruit has its benefits, but fresh fruit is always a better choice if you want to take care of your teeth and gums.

Citrus, Coffee, and Tea

All of these foods and drinks are not bad for you, but you shouldn’t consume the in large amounts. Oranges, lemons, and grapefruits are very healthy, but they contain a lot of acids that can be damaging to the tooth enamel.

Coffee and tea can have a positive effect, but because of the caffeine and theine they can easily stain your teeth if you’re not careful


Alcohol is bad for you in every way possible. When it comes to your oral health, alcohol is damaging because it’s drying and that can be bad for the mucosa and gums.

Too much alcohol can lead to skin peeling inside the mouth. If you drink alcohol sometimes, try to drink enough water to prevent dehydration.


Oral health is important and if you notice anything wrong in your mouth, you have to take care of it as soon as possible. Skin peeling in your mouth is not the worst-case scenario, but it’s not comfortable either.

This article gave you much information about treatment, prevention, and possible causes. Don’t worry, because this condition is usually not serious. You can easily treat it, but make sure to do everything in your power to prevent it in the future.
