Frequently Asked Questions

How often should I get my teeth cleaned?

Most patients need a professional dental cleaning every six months. Some patients may need visits every three to four months based on their gum health and individual dental needs.

Why do I need dental X-rays? Are they safe?

Dental X-rays help us detect cavities, infections, bone loss and other concerns that cannot always be seen during a visual examination. They use very low levels of radiation and are considered safe when proper precautions are followed.

What is the difference between a regular cleaning and a deep cleaning?

A regular cleaning removes plaque and tartar from the teeth and above the gumline. A deep cleaning, also known as scaling and root planing, removes bacteria and buildup beneath the gums to help treat gum disease and prevent it from progressing.

Why do my gums bleed when I brush or floss?

Bleeding gums are often a sign of inflammation caused by plaque buildup or gum disease. Consistent brushing, daily flossing and regular professional cleanings can help reduce inflammation and improve gum health.

What causes cavities?

Cavities form when bacteria in the mouth feed on sugars and produce acids. Over time, these acids can weaken and break down tooth enamel, creating areas of decay.

Do electric toothbrushes work better?

Electric toothbrushes can remove more plaque and may help improve gum health compared with manual toothbrushes. They can also make it easier to brush thoroughly and consistently.

What toothpaste or mouthwash should I use?

We generally recommend using fluoride toothpaste and a fluoride mouthwash. Patients with tooth sensitivity, gum disease, dry mouth or other concerns may benefit from specialized products recommended by our dental team.

Is teeth whitening safe?

Yes, teeth whitening is safe when performed professionally or with dentist-approved products. Some temporary tooth sensitivity may occur during or after treatment.

Why is my tooth hurting if nothing looks wrong?

Tooth pain can be caused by cavities, cracks, gum problems, clenching or grinding, infection and other conditions that may not be visible. A dental examination can help identify the cause and determine the appropriate treatment.

What is the difference between a filling and a crown?

A filling repairs a relatively small area of tooth decay or damage. A dental crown covers and protects the entire visible portion of a tooth when a larger area is damaged, weakened or restored.

Do root canals hurt?

Modern root canal treatment is typically similar to receiving a dental filling. The procedure is performed using anesthesia and is designed to relieve the pain caused by infection or inflammation inside the tooth.

How long do crowns and fillings last?

With proper oral hygiene and routine dental care, fillings may last approximately five to 15 years, while crowns may last 10 to 20 years or longer. Their lifespan depends on the material, location, oral habits and overall dental health.

How can I get rid of bad breath?

Regular dental cleanings, thorough brushing, daily flossing, tongue cleaning and staying hydrated can help reduce bad breath. Persistent bad breath may be associated with gum disease, dry mouth or another oral health concern.

Why is replacing missing teeth important?

Missing teeth can affect your ability to chew and speak comfortably. They may also cause nearby teeth to shift, contribute to jawbone loss and reduce support for the facial structures.

Are dental implants safe? How long do they last?

Dental implants are considered a safe and reliable long-term option for replacing missing teeth. With good oral hygiene and regular dental visits, implants can last for decades.

Why did my filling fall out?

A filling may fall out because of normal wear, decay beneath the restoration, teeth grinding or biting down on something hard. Our dental team can examine the tooth and determine whether the filling should be replaced.

Can I straighten my teeth without braces?

Yes, clear aligners such as Invisalign® may be an effective option for many patients who want to straighten their teeth without traditional braces. A consultation can determine whether clear aligners are appropriate for your needs.

Why is dental treatment expensive?

Dental care involves specialized equipment, high-quality materials, laboratory services, advanced technology and extensive professional training. We can review your treatment options and help create a plan that considers both your oral health needs and your budget.

Does my insurance cover this?

Dental insurance coverage varies depending on the plan and the treatment being provided. Our team is happy to review your benefits and provide an estimate before treatment whenever possible.

How can I prevent future dental problems?

Brush your teeth twice daily, floss at least once a day, use fluoride products, limit sugary foods and drinks and maintain regular dental examinations and professional cleanings.
