Unlike bone, a cracked tooth cannot heal itself. Small cracks may simply need to be monitored, while others may require a filling, crown, root canal, or another treatment depending on their location and severity.

Brush twice daily with fluoride toothpaste, clean between your teeth every day, and limit frequent sugary or acidic foods and drinks. Regular professional cleanings and dental exams can also help identify areas that may be at greater risk for decay.

Tooth sensitivity can become more common as enamel wears or gums recede, but persistent sensitivity shouldn’t automatically be considered a normal part of aging. Cavities, cracks, gum recession, and other dental conditions can also cause sensitivity.

Common early signs include red or swollen gums, bleeding when brushing or flossing, persistent bad breath, and gum tenderness. Gum disease can sometimes develop with few noticeable symptoms, making routine dental exams especially important.

Persistent bad breath can have several causes, including bacteria on the tongue, gum disease, cavities, dry mouth, certain foods, or other health conditions. If brushing, flossing, and cleaning your tongue don’t resolve the problem, a dental examination can help identify the cause.

A routine dental exam typically includes an evaluation of your teeth, gums, bite, and overall oral health. Your dentist will look for signs of cavities, gum disease, damaged teeth, and other concerns. X-rays may also be recommended when needed.

A filling may be appropriate when there is enough healthy tooth structure remaining to support it. A crown may be recommended when a tooth has extensive decay, a large filling, significant damage, or has become too weak to be predictably restored with a filling alone.

The American Dental Association generally recommends replacing your toothbrush or electric toothbrush head every three to four months, or sooner if the bristles become visibly frayed. Worn bristles don’t clean your teeth as effectively.

Many dental problems don’t cause noticeable symptoms in their early stages. Regular dental visits allow your dentist to identify concerns such as cavities, gum disease, or cracked teeth before they become painful or require more extensive treatment.

Bleeding gums are often associated with inflammation caused by plaque buildup or gingivitis. Brushing and flossing consistently can help, but frequent or persistent bleeding should be evaluated by your dentist.
