For the first couple of days after your teeth whitening your teeth are more susceptible to taking up stains from anything you eat or drink, so ideally you might stick to a “white diet” without any artificial or natural colouring in it. You should avoid beverages like tea, coffee, wine, fruit juices, sodas, dark-coloured fruits and anything else that may leave stains on your teeth. You can enjoy curry free protein meals, rice, pudding, pasta, white cheese, white bread, bananas, etc. Just make sure your food is not pigmented.
Mild teeth sensitivity is common while undergoing tooth whitening. The nerves inside your tooth get triggered by the peroxide-based bleaching agents and overreact when they come in contact with hot or cool drinks. In most cases, the hypersensitivity goes away on its own in 48 hours.
Teeth hypersensitivity can be managed using a variety of products available in the market. Usually, dentists prescribe desensitizing toothpaste to minimize post-treatment sensitivity. These desensitizing toothpaste block pain signals from the tooth nerve to the brain and help decrease discomfort. You can also get desensitizing gels to reduce the sensitivity. Rub a small amount of desensitizing gel/toothpaste over the sensitive teeth and leave it on for the recommended time, as per the manufacturer’s instructions. You can even place the desensitizing gel/toothpaste in your whitening trays and leave them on for the required duration of time.
It’s essential to use a soft-bristled brush for brushing and lukewarm water rinsing after your whitening treatment. We recommend using fluoride toothpaste to allow the tooth to remineralize and block the nerve endings inside your teeth. Try to leave the fluoride toothpaste on your teeth for 2-3 minutes before rinsing it off, as this will help the fluoride flow into the teeth much better. For a few days after your treatment, opt out of hot and cold drinks, especially tea and coffee, as this will prevent both staining and teeth hypersensitivity.
