Like other areas of the body, your mouth teems with bacteria — mostly harmless. But your mouth is the entry point to your digestive and respiratory tracts, and some of these bacteria can cause disease.
Normally the body’s natural defenses and good oral health care, such as daily brushing and flossing, keep bacteria under control. However, without proper oral hygiene, bacteria can reach levels that might lead to oral infections, such as tooth decay and gum disease.
Also, certain medications — such as decongestants, antihistamines, painkillers, diuretics and antidepressants — can reduce saliva flow. Saliva washes away food and neutralizes acids produced by bacteria in the mouth, helping to protect you from microbes that multiply and lead to disease.
How can I protect my oral health?
To protect your oral health, practice good oral hygiene daily.
- Brush your teeth at least twice a day with a soft-bristled brush using fluoride toothpaste.
- Floss daily.
- Use mouthwash to remove food particles left after brushing and flossing.
- Eat a healthy diet and limit food with added sugars.
- Replace your toothbrush every three months or sooner if bristles are splayed or worn.
- Schedule regular dental checkups and cleanings.
- Avoid tobacco use.
