Teeth whitening is an aesthetic technique aimed at lightening the color of teeth and restoring their brightness. There are several teeth whitening methods available, including trays, strips, pens, or LED lights. These products typically contain hydrogen peroxide or carbamide peroxide, bleaching agents that penetrate the enamel and break down the pigments that stain teeth.
Teeth whitening can have temporary side effects, such as increased tooth sensitivity or gum irritation. These symptoms occur due to the action of the peroxide on the nerve endings located in the dentin, the layer beneath the enamel. Tooth sensitivity manifests as pain or discomfort when teeth are exposed to thermal (hot or cold), chemical (acidic or sugary), or mechanical (pressure or chewing) stimuli.
Here are some tips:
Choose a product suitable for your sensitivity level. Some products have a lower concentration of peroxide or contain desensitizing agents, such as fluoride or potassium nitrate, which help protect the tooth nerves.
Follow the product's instructions for use. Do not exceed the recommended duration or frequency for treatment. If using a tray, ensure it fits snugly in your mouth and does not overflow onto the gums.
Brush your teeth with a toothpaste for sensitive teeth. This type of toothpaste also contains desensitizing agents that form a barrier on the dentin and reduce the transmission of stimuli to the nerves.
Avoid foods and drinks that are too hot, too cold, too acidic, or too sugary during treatment and for a few days afterward. These substances can worsen tooth sensitivity and affect the whitening result.
Take an analgesic for intense pain. You can take an anti-inflammatory medication, such as ibuprofen or aspirin, to relieve pain and gum inflammation. Consult your doctor or pharmacist before taking any medication.
Consult your dentist if sensitivity persists or worsens. They can advise you on the best product to use or suggest an alternative treatment, such as fluoride varnish or laser therapy.
Teeth whitening is an effective and safe way to enhance the appearance of your smile. However, it's essential to be aware of potential risks and know how to prevent or treat them. If you have any questions or concerns, don't hesitate to seek advice from your dentist.
