Bump on Inside of Cheek Causes: Reasons

Table Of Contents

Bumps on the inside of the cheek are the most uncomfortable thing one can have. Every time you drink or eat something they get irritated. Chances are that you will at some time also bite them too. Bumps in the cheek can be due to various reasons including infections, injuries, stress, digestive problems or allergic reactions.

Bumps in the mouth can be caused by different reasons including:

Food Irritations

A bump inside the mouth can be caused by eating or drinking hot things. Spicy, sour or salty foods also cause bumps inside the cheek. To treat this kind of bumps, make sure that the temperature of things you put in the mouth is just right and that you avoid spicy or salty foods.

Canker Sores

These are ulcers that appear on the cheek in small or large clusters. They start out as painful red bumps which later develop into ulcers that have a white or yellow middle. Before it develops, one gets a tingling or burning feeling on the cheek. The bump can get very swollen and painful

Their exact trigger is not known although hormonal changes, stress, poor diet and food allergies can cause them. Other causes include injuries to the mouth from cheek biting or dental procedures.

Canker sores hurt for around 10 days and can take up to 6 weeks to heal depending on their severity. Some people develop canker sores immediately the other one heals. These bumps inside the mouth usually heal on their own but one can take topical medications for pain relief. Salty water, a mild mouthwash and eating less spicy foods can also decrease pain.

To take care of canker sores:

  • Eat foods that are easy to swallow like yogurt
  • Drink cold fluids from straws so as not to touch the canker sore
  • Brush teeth carefully to avoid touching the sore with your bristles
  • Hold ice to the canker sore to numb it and relieve pain.

A home remedy for this type of bumps is applying baking soda. It soothes and reduces inflammation. Make a paste with 1 tablespoon of baking soda and a little water and apply to the sore for few minutes then rinse off.

Oral Lichen Planus

Oral Lichen Planus is chronic, inflammatory and affects the mucous membrane of the oral cavity. Its causes are unknown although a weak immune system is thought to be the cause.  This is not an infection and cannot be passed from person to person. Oral lichen planus can be caused by drugs, for example, some antibiotics, hypertension drugs, and heart disease drugs. These drugs erupt the skin in the mouth. Other causes include contact from some toothpaste, mechanical trauma or a viral infection like Hepatitis C.

Oral lichen planus presents itself in different modes. There may be white lace-like patterns on the inner sides of the cheek, white and red patches on the cheeks or ulceration areas on the cheeks. This can be very painful and the affected may not be able to eat properly. They also sometimes lead to scars.

You can start treatment by identifying and removing things that may be causing the lichen planus. This can be done by patch testing. If your toothpaste irritates your cheeks, try a different product, quit smoking and use topical chamomile gel to reduce symptoms. Topical steroids like sprays, gels, pastes, and drops can also be used. Steroid injections and mouth rinses that contain calcineurin inhibitors also work.

Mucous Cysts

A mucous cyst is a sac with thin fluid on the inside of the mouth.  It develops when the salivary glands in the mouth get plugged with mucus. The Mucous cyst is also known as mucocele and is painless and harmless.  The mucocele sac contains clear fluid.

Mucous cysts on the cheek are caused by cheek biting, piercings and chronic damage from adjacent teeth.

Treatment may not be required, and the cysts will heal on their own, however, for prevention purposes do not try to remove or open them at home. If they occur frequently, seek medical attention. The doctor can either perform:

  • Laser therapy-where a beam of light is directed at the cyst to remove it.
  • Cryotherapy- where the cysts are removed by freezing it.
  • Intralesional corticosteroid injection-where the cyst is injected with a steroid. This reduces inflammation and speeds up the healing process.
  • Surgery- this is especially if they are recurrent and severe.

Oral Thrush

Small white bumps inside the mouth cheeks caused by yeast infections that develop on the inside of the mouth and tongue. Oral thrush often affects infants and toddlers. The white bumps if scraped, can bleed and cause lots of pain. In toddlers, the thrush makes it difficult for them to feed and makes them fussy and irritable. The infection can be passed to their mothers during breastfeeding.

Treatment depends on age and health and is meant to prevent the fungus from growing and spreading. Treatment of small bumps on cheeks caused by oral thrush can be by using antifungal medication, antifungal mouthwash or amphotericin, a drug that treats severe infections.

Home remedies for oral thrush include

  • Replacing the toothbrush once the infection heals.
  • Using a soft toothbrush when brushing.
  • Rinsing the mouth with a salty mixture.
  • Avoiding mouth sprays and mouthwashes.
  • Eating yogurt (unsweetened) to maintain and restore good bacteria.
  • Rinsing pacifiers and bottle nipples in a vinegar-water solution.
  • Treating both the mother and child to prevent cycle reinfection.

Cold Sores

Cold sores are blister-like lesions caused by the herpes simplex virus. They appear as bumps on the inside of the cheek. The bump will then start as itching, tingling burning sensation on the cheek which is followed by a fluid-filled sore, that can start to swell. The cold sore mostly appears on the same spot every time and when it breaks, it oozes, which could spread the infection.  Most of them disappear on their own within a week or two.

Treatment can be through over the counter antiviral creams, or medications which help shorten the duration of the outbreak while reducing pain and discomfort. Oral medications, painkillers can also be used to alleviate pain.
