Burned gums from teeth whitening occur when soft oral tissues come into contact with whitening agents like hydrogen peroxide or carbamide peroxide. This exposure can cause discomfort, redness, swelling, and white or sore spots on the gums.
Immediate Steps and Home Care
If gum irritation occurs during teeth whitening, immediately stop the treatment and remove any product. Rinse thoroughly with cool water to remove residual gel. A warm saltwater rinse (half a teaspoon of salt in one cup of water, swished for 20-30 seconds, 2-3 times daily) can cleanse the area, reduce inflammation, and promote healing.
To alleviate discomfort, apply a cold compress to the outside of your cheek near the affected area for 10-15 minute intervals. This reduces swelling and numbs pain. Over-the-counter pain relievers such as ibuprofen or acetaminophen manage discomfort and inflammation. Oral anesthetic gels containing ingredients like benzocaine, such as Orajel or Anbesol, provide temporary numbing relief when applied directly.
For soothing remedies, gently apply pure aloe vera gel to the burned gum tissue two to three times daily. Aloe vera possesses anti-inflammatory and antibacterial properties that can aid healing and reduce swelling. Similarly, vitamin E oil can be applied directly to the affected gums to help reduce inflammation and promote tissue repair.
During the healing period, eat soft foods and avoid irritants such as hot, cold, spicy, acidic, or crunchy foods and drinks. Continue practicing gentle oral hygiene using a soft-bristled toothbrush to avoid further irritation, and consider switching to a sensitive toothpaste.
When to See a Dentist
While minor gum irritation from teeth whitening often resolves with home care within a few days, certain signs indicate the need for professional dental attention. Seek a dentist if you experience severe or persistent pain, discomfort that worsens despite home remedies, or signs of infection like pus, fever, or increased swelling.
A dentist can assess the burn and determine necessary treatment. They may prescribe stronger medications, such as antibiotics for infection or non-OTC pain relievers. In some cases, protective gels or barriers might be applied to shield affected areas and promote healing. If the burn resulted from a professional whitening treatment, contact the dental office for guidance and follow-up care.
Preventing Future Gum Irritation
Preventing future gum irritation involves careful product selection and proper application techniques. Choosing whitening products with lower peroxide concentrations can significantly reduce the risk of gum burns, especially for individuals with sensitive gums.
Always follow the product instructions precisely, paying close attention to the recommended application time and frequency. Overuse or leaving the whitening gel on for longer than directed increases the risk of irritation. When using whitening trays, avoid overfilling them, as excess gel can seep onto the gums. Wiping away any excess gel that contacts the gums immediately with a finger or tissue can help prevent irritation.
Using custom-fitted whitening trays, ideally provided by a dentist, can help ensure the gel stays on the teeth and away from the gums. If using whitening strips, trimming them to fit only the teeth and avoiding direct contact with the gum line is beneficial. Applying a protective barrier like petroleum jelly to the gums before whitening can also shield them from the bleaching agent. Consulting with a dentist before starting any teeth whitening regimen allows for an assessment of oral health and personalized recommendations to protect your gums.
