Is teeth whitening safe?  In general as long as one has fairly healthy gums, teeth whitening is safe and usually very effective.  It’s also one of the easiest and most rewarding parts of cosmetic dentistry!

With in-office same day whitening (ie. ZOOM or BOOST) your dentist in Bellevue will typically use a very high concentration of hydrogen peroxide to whiten your teeth.  Though results can vary, people are usually happy with the results and can usually have their teeth whitened 2-3 shades lighter, sometimes even more! Over the counter whitening products typically do not whiten as well, but may be worth trying (Crest White Strips is a good over the counter product to try).  The most common side effect is sensitivity, but it usually goes away 1-2 days after the whitening procedure.

What is the difference between a silver filling and white filling?  A silver filling, also known as an amalgam restoration, is a combination of different metals/elements combined together.  It leaves the factory as a liquid, and once mixed at a high speed, it sets into a hardened state.  A white filling, or tooth colored filling, is composed of small particles of glass and resins.  When applied to the teeth, it feels soft; we then use a ultraviolet light to harden the material.

Why do you need to take x-rays?  Your dentist will discuss with you how often to take xrays. X-rays are taken to evaluate for presence of cavities, any bone disease, tooth infection, abnormal bone pathologies, etc.

There’s too much radiation in x-rays, I don’t want them.  With the advent of digital xrays, there is now up to 90% less radiation than that compared to tradional film xrays.  One will actually get more radiation by walking out in the sun, or from flying in an airplane.  Rest assured the xrays taken at the dental office is at very low and safe level.

The cavity doesn’t hurt, I don’t want to get it fixed.  Sometimes if a cavity is small, with proper hygiene and flouride, it may heal and never need treatment. Other times if a cavity is large enough though, there is risk of it getting bigger, and possibly causing pain and, in worst case scenario, future need for a root canal and crown.  Getting the cavity removed and filled ensures better long term predicability.  Your dentist can discuss with you the appropriate and recommended treatment.

Why do I need to get a cleaning and checkup every 6 months? Oral health studies have shown that cavities may take 4-6 months to develop.  If we catch them early, they are often easier to treat and with greater predicability. Cumulative studies in dental medicine have also shown that most levels of plaque and tartar buildup takes 3-6 months to accumulate.  Routine checkups and cleaning is generally the best way to be proactive, preventive, and to save on costs as well.

Why do I need a crown?  If a tooth is fractured or cracked, or if there is a large enough filling that is going bad, sometimes a tooth a crown or “cap” is needed to allow proper chewing and to prevent further fractures.  Due to chewing forces, crowns or “caps” tend to be more frequently needed on posterior teeth (back molars and premolars).

What type of training is required to be a dentist?  In the United States, a general dentist attends a university in an undergraduate program to acqurie a bachelors degree, usually 4 years.  Then an additional 4 years at an accreditted dental school is done, resulting in a Doctorate in Dental Surgery (DDS) or Doctorate in Dental Medicine (DMD).  Many then choose to attend a 1-2 year residency (GPR) to further enhance their training.  Specialists (ie. oral surgeons, endodontists) usually go for an additional 2-7 years after dental school.  Rest assured, your local dentist is trained and well versed to treat your oral health needs.
