Why Do I Keep Getting Pimples Inside My Lip?

Bumps inside your lip often look like pimples. Despite the similar appearance, these bumps are called mucous cysts (or mucoceles).

They’re usually harmless and often heal on their own. But if you have one that is causing discomfort, won't go away, or gets infected, it's always a good idea to check in with your dentist or doctor for guidance.

What Do Mucous Cysts Look Like?

Mucous cysts are fluid-filled sacs that can develop on the inner lining of your lips, the roof of your mouth, or even under your tongue. The cysts usually look like a clear, bluish, or pinkish bubble.

Most are small, about the size of a pea, or even smaller. They're soft to the touch and mostly painless, although a large one can be a bit bothersome.

What Causes Mucous Cysts?

The most common culprit of mucous cysts is minor injuries or repetitive trauma to the inside of your mouth. Do you tend to bite your lip or accidentally chew on your inner cheek? These habits can irritate the tiny glands (salivary glands) that produce saliva, leading to the development of cysts.

Other causes include blockages. Sometimes, a salivary gland duct can get blocked. A duct is like a little pipe that carries the saliva; when it gets plugged up, the saliva has nowhere to go but out into the surrounding tissue, creating a cyst.

While not a direct cause, poor dental hygiene can also create conditions where bacteria thrive. This bacteria can infect an already damaged salivary gland, thus causing an infection.

Diagnosis and Treatment Options

If you have a bump inside your lip, your first step should be to see a dentist or doctor. While these are often harmless mucous cysts, getting a proper diagnosis and ruling out any other underlying conditions is important.

How Is a Mucous Cyst Diagnosed?

Diagnosis is usually straightforward. First, your doctor or dentist will take a close look at the bump and ask questions about your medical history and any associated symptoms.

They'll likely ask if you've recently bitten your lip or if you tend to do it habitually, as these are common culprits. In rare cases, your doctor might suggest a biopsy (removing a tiny sample of tissue) to rule out any other problems.

What Are My Treatment Options?

The best course of action depends on how bothersome the cyst is, how long it lasts, and whether it keeps coming back. 

Don't try to pop or drain a mucous cyst yourself. This can increase the risk of infection. Always talk to your doctor for the safest and most effective approach based on your situation.

Here's an overview of possible treatments:

Home Remedies

Before seeking professional treatment, you can try these home remedies to encourage healing and alleviate discomfort from mucous cysts:

• Time: Many mucous cysts heal on their own with a little time, often within a few weeks.
• Warm Saltwater Rinses: Can promote healing and help ease any discomfort 
• Avoiding Trauma: Try to be extra mindful of lip or cheek biting to prevent further irritation.

Prescription Medications

If the bump is a cold sore (caused by a herpes virus), antiviral medications can help. These medications, such as acyclovir, are available as pills or creams and can speed up healing.

Professional Procedures

Your doctor or dentist might recommend one of these if the mucous cyst is persistent, painful, or keeps returning:

• Surgical Removal: The cyst and/or the associated salivary gland might be completely removed to prevent a recurrence.
• Laser Therapy: A focused beam of light removes the cyst. This can be less invasive than traditional surgical removal. 
• Cryotherapy: Extremely cold temperatures can destroy the tissue of the mucous cyst. 
• Steroid Injections: Injections into the cyst can shrink it down and reduce inflammation.
• Marsupialization: Creating an opening in the cyst helps it drain continuously, allowing the formation of a new duct from the salivary gland to the oral cavity, which can prevent the cyst from reforming

How to Prevent Pimples Inside Your Lips

While there's no foolproof way to stop pimples inside your lips, some simple changes can make a big difference. Here's a proactive plan for you to try out:

Practice Good Oral Hygiene

Brushing twice daily and flossing at least once are essential for combating harmful bacteria and maintaining oral health.

A harsh toothpaste or mouthwash can irritate your lips, so look for SLS-free or sensitive formulas. After getting sick, swap out your old toothbrush to prevent reinfection.

Avoid Potential Triggers

Various factors can trigger pimples inside your lip. The biggest trigger is biting your lip. Also, oily or greasy foods might worsen acne for some. Pay attention to what you eat and see if you can spot any patterns.

You should also be careful about thick lip products—some balms and lipsticks contain ingredients that can clog pores. 

Some lip bumps can also be caused by allergies to food, makeup, or even dental products. If you suspect an allergy, try to identify what might be triggering the reaction.

Practice Self-Care

Self-care can also help prevent pimples on your lips. Some extra tips include: 

• Find healthy ways to manage stress, such as exercise, a calming walk, or a few minutes of deep breathing.
• Drink plenty of water and apply a plain lip balm to prevent your lips from becoming dry and irritated.
• Avoid picking or touching your lips. The more you do so, the more likely you are to introduce bacteria and worsen irritation.
