Why do I need x-rays?

X-rays are needed to detect cavities, bone loss, and gum disease problems that can lie below the surface undetected by even a thorough visual exam.

Does your office perform dental implant surgeries?

Yes. Dr. Kassan has been placing dental implants for over 25 years.

Does your office perform root canals?

Yes. Dr. Kassan has performed thousands of root canals over his 30+ years in practice.

What is a root canal?

A root canal removes the sick or dead nerve in the tooth and replaces it with a filling material that acts like a cork in a bottle, sealing the inside of the root shut to prevent bacteria from living there.

How would I know if I'm grinding my teeth? What happens to them if I grind my teeth at night?

Teeth grinding is very common, with one out of every three people doing it in their sleep. The dental term for it is bruxism. If you are waking up with sore teeth, sore muscles in your face, or a stiff jaw, you are grinding your teeth at night. We see evidence of this when teeth have worn spots, cracks or even teeth shifting from all the force applied every night. A person can put anywhere from a week to a whole month of wear on their teeth every night depending on the severity of their grinding. Believe it or not, some people aren’t aware that they are damaging their teeth with grinding until we diagnose it for them after seeing the evidence described.

How is teeth grinding treated?

The only true way to protect your teeth from grinding at night is to have an oral appliance made. There are several forms of these. The appliance recommended is tailored to your specific needs.

A retainer is an appliance that’s made to fit over your teeth to keep them from moving. They are usually made after you finish orthodontic treatment (braces). We make replacement retainers for patients that have worn out their old ones or have had enough dental work that their original retainer no longer fits.

Why should I get the space filled in where the tooth was taken out?

If you are left with a space between teeth where a tooth was taken out, it should be restored with either a dental implant or a bridge. This will keep the teeth adjacent to the space and the teeth above or below the space in check, so they don’t shift and affect your bite.

What is a crown? When do I need a crown?

A crown is like a new layer of enamel for a weakened tooth. When a tooth fractures or gets a crack in it, the tooth needs to be splinted together so it doesn’t split in half. Teeth that have been hollowed out by having a root canal performed also need to be reinforced by having a crown put over them. Teeth that have too much original tooth structure missing from a large deep cavity, or being filled and refilled too many times, cannot hold a filling. They require crowns to restore their strength so that they hold up to chewing forces.

What's a porcelain veneer? Does your office offer porcelain veneers?

A porcelain veneer is a new layer of enamel covering the front and top of your teeth. They’re used to correct chipped teeth, discolored teeth or to close spaces in between front teeth. Dr. Kassan has over 30 years of experience in this field.

What's the difference between getting a bridge to replace a tooth and getting a dental implant to replace the tooth?

Both have a very high success rate and have their own advantages as well as disadvantages. A dental implant replaces the missing tooth without having to involve the adjacent teeth. It requires surgery to place the implant and 3 months for the bone to grow onto the surface of the implant before you can attach a crown to it and use it. A bridge requires trimming the adjacent teeth in front and behind the space to use as crowns that hold up a floating porcelain tooth in the middle to replace the tooth that’s missing. It can all be completed in 2-3 weeks and doesn’t require surgery.
