Canker Sores Care

Canker Sores Care

Canker sores are small white erosions or sores surrounded by a reddened area.

Although canker sores are not contagious, they are often confused with cold sores, which are caused by the herpes virus. It may be helpful to remember that canker sores appear inside the mouth, while cold sores usually appear outside of it. Canker sores are bumps, spots or sores on the mouth, lips or tongue.

If you have a canker sore in your mouth, you are not alone: about one third of all people suffer from this at some point. However, sores, irritations and oral lesions are painful, unsightly, and can interfere with feeding and speech. Any mouth sore that lasts over a week should be examined by a dentist.

Canker sore treatment

Canker sores usually heal after 7 or 10 days, although recurrent outbreaks are common. Over-the-counter topical ointments and analgesics provide temporary relief, and the use of antimicrobial mouth rinses also help to reduce the irritation. Sometimes, antibiotics are prescribed to reduce a secondary infection.

How to prevent canker sores

Cleaning dental prostheses well is important to prevent problems induced by them. It is always recommended to remove the prosthesis at night.

If the cause is the use of antibiotics or oral contraceptives, you may need to reduce the dosage or change treatments.

If the cause is dry mouth, you should learn there are saliva substitutes to treat this condition.
When the underlying cause is inevitable or incurable, you can use anti-fungal medications.

Keeping a good oral hygiene is basic to avoid canker sores, so make sure to schedule your regular dental checkup with Dr. Moretta by calling 714-848-4247.
