To maintain good oral hygiene, you should brush your teeth with a fluoride toothpaste two to three times a day, once in the evening. At least 2 minutes should be spent to ensure proper cleaning. You can supplement your oral hygiene routine using a tongue cleaner, an interdental brush and a mouthwash to reach the less accessible corners.
The toothbrush bristles wear over time, so it is advisable to change the brush every 3 months or sooner if there is obvious deterioration. Remember that if the end of the bristles is very deteriorated, it may not provide optimal cleaning and may cause micro trauma to your gums.
Go for regular check-ups with your dentist to ensure good oral health and hygiene.
