Most teeth whitening treatments last for around one to two hours. However, there are some treatments that can last up to four hours. There are also some at-home kits that need to be used for a period of time each day over the course of a week or more.
Are there side effects from teeth whitening?
Side effects from teeth whitening are usually temporary and include sensitivity, gum irritation, and whitening of the surrounding skin.
Dental hygiene tips
To help keep your teeth white, practice good dental hygiene by brushing twice a day, flossing daily, and using a whitening toothpaste. You should also avoid foods and drinks that can stain your teeth, such as coffee, tea, and red wine.
Diet tips for white teeth
Eating crunchy fruits and vegetables can also help to remove surface stains from your teeth. So, include foods like apples, celery, and carrots in your diet.
If you have sensitive teeth, there are some at-home whitening kits that come with a desensitizing gel. You can also ask your dentist about in-office whitening treatments that can be done with a lower concentration of bleaching agent.
