Biting your lower lip or tongue is something that generally occurs suddenly. You may just be eating when you make a mistake and bite yourself, causing an injury to yourself. You might potentially bite yourself if you are in a car accident or otherwise injure yourself elsewhere.

Because the mouth contains a plentiful supply of blood, a bite of this kind might result in significant bleeding. The majority of the time, it just causes discomfort and swelling. Because of the abundant blood flow to the mouth, mouth wounds heal rather fast.

However, there are several cases in which biting down on your lip or tongue necessitates seeking medical assistance. In this post, we will talk about the actions you may take at home and when you should seek professional assistance.

What causes mouth wounds to occur?

Cuts on the lips, tongue, and interior of the mouth are something that virtually everyone experiences at some point in their lives. As a result, even the tiniest bump or scratch may cause the skin to break in these locations. This is because they are the most delicate on your body. 

You could have received cuts on the inside of your mouth from your teeth cutting into it. Alternatively, you might have damaged your lips from accidently biting down. Some ulcers on the inside of the lips are canker sores or cold sores.

Whatever it is, you must be wondering how to heal a bitten lip inside the mouth. Let’s talk more about it.

The majority of incisions on the inner or outer lip are small. A fall or a vehicle collision might result in more severe injuries, such as a facial injury requiring medical attention. It is in these cases that you should contact your dentist to get the wound examined.

To feel or see a wound in your mouth for the first time might be frightening. This is because they tend to bleed more profusely than a cut on another area of your body. 

Because that skin is delicate and sensitive, as well as being near to blood arteries, the quantity of bleeding will be increased. It is critical to maintaining appropriate dental hygiene in this region in order to aid in the healing process.

Symptoms of Mouth Wounds

It may be quite painful to bite the inside of your lip. It often occurs by chance, and it is particularly prevalent in young children. 

It’s possible that you’ll bite the inside of your lip:

  • While driving, eating, or conversing
  • Following a fall, collision, or another mishap while participating in sports
  • While experiencing a seizure due to stress

Despite the fact that the injury might be painful, it is typically not serious enough to need medical treatment. If you ask an expert about how to heal a bitten lip inside, he might suggest self-care. Self-care procedures may be used to treat a small bite that has occurred at home.

How does it feel when you bite the inside of your lower lip?

Furthermore, if the bite punctures your skin, you may experience a significant amount of blood loss. This is due to the fact that your lips contain a plentiful flow of blood.

Other signs and symptoms of a bitten lip are as follows:

  • Swelling 
  • Soreness
  • Sensitivity

It may also result in injuries such as the following, depending on the power of the bite such as cuts, pimples, canker sores, and mucocele (mucus-filled cyst), etc.

How to Heal a Bitten Lip Inside Your Mouth?

The following actions should be followed if you have bitten your lip or tongue:

Clean Any Debris

When you bite your lip or tongue, check the area for any debris, especially if the injury was caused by a fall. If there is any debris, clean it with gauze. Using a clean piece of gauze, carefully clean the affected area. 

Remove Any Material (if present)

If there is material lodged within the incision, do not try to remove it. Instead, seek medical attention. Consult with a physician.

Clean the Wound

You may clean the wound even more by rinsing your mouth with salt water afterward. It is also possible for adults to use a solution of one part hydrogen peroxide to one part water if they so want. 

Children, on the other hand, should not be given this rinse since they may ingest it.

Control the bleeding

Control any bleeding that may occur. With a clean piece of gauze or a clean cloth, apply hard pressure to the cut to stop the bleeding. When you can’t get the bleeding to stop, keep applying pressure to the area.

Apply a Cold Compress

Immediately after the bleeding has stopped, apply a cold compress to the wound to help minimize the amount of edema.

Prevent Infection

To protect an injury within the mouth from becoming infected, you may use a popsicle to keep the spot cool or place ice cubes inside your mouth.

How to Manage Symptoms of a Bitten Lip?

You may begin taking the following procedures to control symptoms and avoid infection as soon as you get the bite. Let’s get to how to heal a bitten lip inside the mouth while managing its symptoms.

Use Salt Water and Rinse

Apply a Cold Compress to the Affected Area

Applying an ice cube to the inside of your lip might help to reduce swelling. Using an ice pack should be wrapped in a clean towel before application.

Take Pain Relievers Available Over-The-Counter (OTC)

Nonsteroidal anti-inflammatory medicines (NSAIDs), such as ibuprofen, aspirin, and naproxen, may be used to relieve discomfort and reduce swelling in the joints.

Apply an antibacterial gel to the mouth. An over-the-counter oral antiseptic gel is effective against germs that cause illness. Many of these gels are also effective pain relievers.

Tips to Follow During The Healing Process

Avoid vigorous brushing or flossing in the vicinity of the afflicted region. Do not use mouthwashes containing alcohol, which might cause stinging. The same holds true for meals that are acidic, spicy, crunchy, or extremely salty.

To protect from any braces near the cut, get some orthodontic wax from your local drugstore and spread it over them. This will aid in the prevention of the wound from reopening.

Which Mouthwash Is the Most Beneficial for You?

Which mouthwash should I be using is arguably the most often asked question that dentists get. The solution is often dependent on your specific requirements. 

Although most people think of mouthwash as a breath freshener or a way to avoid bad breath, it may also be used to treat other conditions such as bleeding gums and dental decay, as well as to whiten teeth.

One common myth is that mouthwash may eliminate plaque from your teeth and gums. This is just not true. 

Mouthwash swishing may have an antibacterial effect, but it will not eliminate plaque on its own, thus it should never be used in lieu of brushing and flossing. So the question of how to heal a bitten lip inside is well answered by mouthwash use.

Before using any mouthwash, you should consider the following:

  • Identify the key purpose for taking mouthwash and write it down. 
  • Is it for the purpose of treating an illness or merely preventing dental disease?
  • Consult your dentist for further information. 
  • Before taking a mouthwash, you should first seek medical attention for your ailment.
  • Take a close look at the label
  • Be as thorough as possible in your research about the product’s ingredients.

Types of Mouthwashes

Alcohol Containing Mouthwash

Alcohol is one of the most often used substances in mouthwashes. Although it is believed that alcohol kills germs that cause illnesses in the mouth, the alcohol in mouthwash is not the active element in the product. 

Alcohol is added in order to aid in the diffusion of other active substances, such as essential oils. The majority of alcohol-based mouthwashes are intended to freshen breath while also combating bleeding gums and gum disease.

The presence of certain kinds of bacteria in the mouth is the cause of bleeding gums and poor smell. The difficulty is that little is known about the exact mechanism of action that alcohol has on these organisms and how it works. 

Most people assume that alcohol breaks bacterial cell walls. However, no one knows for certain if it is useful against the germs that cause gum disease and foul breath. When working on how to heal a bitten lip inside the mouth, don’t use alcoholic mouthwashes.

Alcohol mouthwash has sparked significant concern due to the possibility that its alcoholic content might be a risk factor for oral cancer. Consuming alcoholic beverages makes the mouth’s cells more sensitive to cancer-causing chemicals.

When alcohol is broken down, the substance produced is acetaldehyde, which is a proven carcinogen in humans. There may be brief negative effects from using alcoholic mouthwash, including the following:

  • Taste disturbances
  • Teeth staining
  • Dry mouth
  • Foul breath

Because they dry out the mouth more than other mouthwashes, alcohol-containing mouthwashes may exacerbate dry mouth and halitosis. It is possible to have soreness, ulcerations, and redness.

Make every effort to avoid using alcoholic mouthwashes. They are not especially useful in the treatment of gum disease or foul breath, and they may even increase the chance of developing oral cancer in certain cases.

Chlorhexidine Containing Mouthwash

Chlorhexidine is an antibacterial compound that is used as an active component in certain mouthwash brands to kill microorganisms. It is an antibiotic with a wide range of activities. It is particularly effective against bacteria that cause gum disease.

Dentists do sometimes use chlorhexidine mouthwash to treat patients who are suffering from gum disease. It reduces inflammation caused by periodontal bacteria. Hence, if you ask a dentist how to heal a bitten lip inside, he might most likely recommend these mouthwashes.

One source of worry is that chlorhexidine may not be as efficient as it should be against the specific germs that cause foul breath.

The use of chlorhexidine mouthwash for an extended period of time has been linked to swelling of the teeth and tongue. It may also produce a dry mouth as a result of altering or decreasing taste. 

Some individuals may see an increase in the accumulation of tooth tartar as a result of this treatment. It is possible that this is linked to changes in oral microorganisms. It may also interact with the components in toothpaste, thus it should always be used in a separate container.

Fluoride Containing Mouthwash

Mouthwash with Fluoride Many forms of mouthwash includes fluoride, which may assist to prevent tooth decay. Fluoride has been demonstrated to be useful in reducing tooth decay, with dental deterioration reduced by five to fifty percent when fluoride is used.

However, it should only be used in the most serious of situations.

Hydrogen Peroxide Containing Mouthwash

Hydrogen peroxide is the active chemical used in the majority of cleaning products used in the home. Because of its oxidizing chemical activity, it possesses a broad range of anti-microbial characteristics. 

Oxidation causes bacterial cells to get damaged and die. It is well known that hydrogen peroxide may cause damage to the cells of the tooth pulp.

It has the potential to cause the tooth nerves to get infected and die as a result (called pulpitis). Make every effort to avoid using hydrogen peroxide mouthwash.
