Why Gum Turns White after Whitening?


|   Written by:


Whitening or bleaching procedures have become a popular method to improve the appearance of teeth. However, an unexpected side effect that some individuals experience is the temporary whitening of the gum tissue. This article aims to shed light on the reasons behind this phenomenon and its implications on oral health.

The causative factors behind gums turning white after undergoing teeth whitening procedures are multifaceted, ranging from the type of whitening agent used, the concentration of the agent, the duration of exposure, and the individual’s gum sensitivity. Despite the alarming appearance, this condition is typically temporary and reversible.

Teeth Whitening Procedures and Their Impact

Teeth Whitening Processes

Teeth whitening is a cosmetic dental procedure aimed at reducing discoloration and staining, or simply providing the patient with whiter and brighter teeth. The process can be done professionally in a dental office, or at home using over-the-counter products. Regardless of the method, the whitening agents used typically contain peroxide compounds—either hydrogen peroxide or carbamide peroxide—that oxidize stains on the tooth surface, thereby lightening the color of the teeth.teeth whitening process

The Impact on Gums

While the whitening agents are designed to act on the teeth, they can inadvertently come into contact with the gums, leading to a reaction that causes the gums to turn white. This reaction is not a result of the whitening process itself, but rather a side effect of the peroxide-based bleaching agents used in these procedures.

The contact of the gums with these agents can cause what is known as “chemical burn” or “tissue irritation”, which manifests as a whitening of the gum tissue. The degree of whitening varies from person to person and is dependent on several factors, including the strength of the whitening agent used and the duration of exposure.

The Role of Peroxide-Based Bleaching Agents

Peroxide-Based Bleaching Agents

Hydrogen peroxide and carbamide peroxide are the two most common active ingredients used in both professional and home teeth whitening products. They work by penetrating the porous surface of the enamel and breaking down stain compounds. However, these chemicals can also interact with oral soft tissues, leading to some degree of irritation or inflammation.

How They Affect the Gums

When these peroxide-based bleaching agents come into contact with the gums, they can cause the outermost layer of cells (the epithelium) to become irritated and temporarily lose its natural coloration, leading to a white appearance. This is a form of mucosal irritation or chemical burn, similar to what can happen when other types of strong chemicals come into contact with the skin.peroxide teeth whitening gel on teeth

It is important to note that the concentration of the whitening agent plays a significant role in the degree of gum whitening. Higher concentrations of peroxides are more likely to cause gum whitening and irritation. For example, a 2012 study published in the Journal of American Dental Association showed that higher concentrations of peroxide-based bleaching agents were associated with increased risks of tooth sensitivity and gingival irritation.

How To Prevent and Protect Burned Gums From Teeth Whitening

Preventing and protecting your gums from burns during teeth whitening involves a combination of careful preparation, proper procedure, and post-treatment care. Here are some useful tips to ensure a safe and effective teeth whitening process:

1. Choose Your Whitening Method Wisely

Not all teeth whitening methods are created equal. In-office professional whitening treatments usually offer the highest level of control and safety. Dentists use protective barriers to shield the gums from the whitening agents, thereby minimizing potential damage. If you opt for at-home whitening kits, choose those from reputable brands and follow the provided instructions meticulously.

2. Limit the Amount of Whitening Agent

Overuse of whitening agents is a common cause of gum burns. Always use the recommended amount of product. More is not necessarily better when it comes to teeth whitening, and can lead to increased sensitivity and gum irritation.

3. Apply the Product Carefully

If you’re using an at-home kit, make sure to apply the product carefully to avoid contact with your gums. For whitening strips, it might be beneficial to trim them so they fit your teeth better and reduce the likelihood of gum contact.

4. Monitor Your Time

Leaving whitening products on for longer than advised in the hope of achieving better results can lead to gum burns. Always stick to the recommended time to avoid over-exposure to the bleaching agents.

5. Aftercare is Crucial

Rinse your mouth thoroughly after each whitening session to remove any residual bleaching agent from your gums. Using an alcohol-free mouthwash can help soothe the gums and keep your mouth fresh.

6. Use Sensitivity Toothpaste

Toothpastes formulated for sensitive teeth often contain ingredients like potassium nitrate or strontium chloride, which can help soothe irritated gums. Consider switching to one of these toothpaste varieties during your teeth whitening process.

7. Maintain a Gum-Healthy Diet

Eating a balanced diet rich in vitamins C and K can support gum health. These vitamins aid in repairing connective tissue and promote healing, which can be beneficial if your gums are irritated from the whitening process.

How to Soothe Irritated Gums

Whether it’s from teeth whitening, aggressive brushing, dental procedures, or other causes, irritated gums can be uncomfortable and painful. Here are some tips to help soothe and heal irritated gums:

1. Salt Water Rinse

Rinsing your mouth with warm salt water can help soothe inflamed gums and reduce bacteria in the mouth. Just dissolve half a teaspoon of salt in a cup of warm water, swirl it around your mouth for about 30 seconds, and spit it out.

2. Cold and Warm Compresses

Applying a cold compress to the outside of your mouth can help reduce gum inflammation and numb the area, providing temporary relief from pain. Following up with a warm compress can stimulate blood flow and promote healing. Be sure to wrap your cold or warm compress in a clean cloth before applying it to your face.

3. Over-the-Counter Pain Relievers

Non-prescription pain relievers can help manage the pain associated with irritated gums. Always use these medications according to the package instructions.

4. Topical Gels and Ointments

Over-the-counter topical gels or ointments can provide temporary relief from gum irritation. These are usually applied directly to the affected area. Some contain numbing agents like benzocaine, which can dull the pain.

5. Oral Hygiene

Maintaining good oral hygiene is crucial. Brushing with a soft-bristle toothbrush and flossing gently can help prevent further irritation and promote healing. Using an alcohol-free mouthwash can also help by killing bacteria and soothing the gums.

6. Hydration

Staying hydrated can help keep your mouth moist, promoting the production of saliva, which naturally helps to cleanse your mouth and reduce irritation.

7. Avoid Irritants

Try to avoid irritants such as tobacco, alcohol, and spicy or acidic foods, as they can further irritate your gums.

8. Use Toothpaste for Sensitive Teeth

Toothpaste designed for sensitive teeth often contain ingredients that can soothe irritated gums. They also help to protect your teeth and gums from potential irritants.

9. Use Desensitizing Gel

Desensitizing gels are specially formulated to reduce sensitivity and discomfort in the gums. These gels often contain active ingredients like potassium nitrate or fluoride, which can help to soothe irritated gums and strengthen tooth enamel. Follow the instructions on the product packaging for proper application.desensitizing gel on teeth

Final Words

While the temporary whitening of gums after a teeth whitening procedure can be alarming, understanding the cause can alleviate concerns. It is primarily a reaction to the peroxide-based bleaching agents used in the whitening process, and factors such as the concentration of the agent and the duration of exposureplay significant roles. Although individual sensitivity can heighten the reaction, in most cases, the condition is harmless and temporary.

Educating patients about this potential side effect, taking measures to minimize gum exposure to the bleaching agents, and following appropriate aftercare procedures can significantly reduce the incidence and severity of gum whitening post teeth whitening procedures.

In the pursuit of a dazzling smile, it’s essential to remember that oral health should not be compromised. Dental professionals and individuals seeking teeth whitening should be aware of the procedures’ potential side effects and manage them appropriately to ensure a safe and effective outcome.

In the broader context, research and innovation in the field of dentistry continue to evolve, aiming at methods that offer maximum efficacy with minimal side effects. Future teeth whitening procedures may likely incorporate advanced techniques to specifically target teeth without affecting surrounding oral tissues, thus making the journey towards a brighter smile a more comfortable and worry-free experience.

In conclusion, while the phenomenon of gums turning white after teeth whitening can be disconcerting, it is typically a benign and temporary condition. By understanding the reasons behind it and following preventative measures, it is possible to achieve the desired aesthetic results without undue concern. As always, any dental procedure should be undertaken with a thorough understanding of the process and potential side effects, and under the guidance of a qualified dental professional.
