Common Problems


Cavities / Tooth Decay

Tooth decay is preventable with proper hygiene. Tooth decay is a result of the acid produced by bacteria in your moth. Proper removal of food particles and plaque can help to minimize acid production. Undiagnosed, severe tooth decay can lead to root canal therapy or tooth loss. 

Sensitive Teeth

Your teeth expand and contract in reaction to changes in temperature. Hot and cold food and beverages can cause pain or irritation to people with sensitive teeth. Over time, tooth enamel can be worn down, gums may recede or teeth may develop microscopic cracks, exposing the interior of the tooth and irritating nerve endings. Just breathing cold air can be painful for those with extremely sensitive teeth.

Periodontal (Gum) Disease

Periodontal disease can range from mild gingivitis to severe periodontitis. Signs of gingivitis include inflamed, red, or bleeding gums while brushing, as well as bad breath. Progression of periodontal disease can lead to bone loss, in turn causing mobile teeth and eventual loss of teeth. Early diagnosis by a dentist can minimize risks of disease.

Bad Breath (Halitosis)

Proper and daily flossing, brushing, and use of a mouth rinse will decrease the amount of build up and odor causing bacteria. Minimum twice yearly cleanings are recommended to remove persistent build up and assess for periodontal (gum) disease. If there is persistent bad breath, it may be an underlying sign of periodontal disease or medical condition. 

Canker Sores

Canker sores (aphthous ulcers) are small sores inside the mouth that often recur. Generally lasting one or two weeks, the duration of canker sores can be reduced by the use of antimicrobial mouthwashes or topical agents. The canker sore has a white or gray base surrounded by a red border.

Orthodontic Problems

A bite that does not meet properly (a malocclusion) can be inherited, or some types may be acquired. Some causes of malocclusion include missing or extra teeth, crowded teeth or misaligned jaws. Accidents or developmental issues, such as finger or thumb sucking over an extended period of time, may cause malocclusions.
