With modern anesthetics, new generation pain killers and advanced technology, endodontic prodecures are very comfortable.  In fact, endodontic treatment usually relieves patients from the pain.  After the treatment, it is common to experience minimal discomfort in the area for a few days.  If the patient is apprehensive , oral sedatives as well as nitrous oxide gas are available to make the visit even more comfortable.

The fee for endodontic treatment is generally determined by the complexity of the situation.  You will be informed of the endodontic fees before any treatmentis started.  For your convenience, we accept all major credit cards, checks and cash.  Payment plans are available through third parties with no interest for three months.  If you have dental insureance we will be happy to complete the forms for your convenience, so that you can be reimbursed as quickly as possible.

Almost always, the endodontic treatment is one visit, lasting one to two hours.

Since teeth whitening has now become the number one aesthetic concern of many patients, there are many products and methods available to achieve a brighter smile.

Professional teeth whitening (or bleaching) is a simple, non-invasive dental treatment used to change the color of natural tooth enamel and is an ideal way to enhance the beauty of your smile.  Over-the-counter products are also available, but they are much less effective than professional treatments and might not be approved by the American Dental Association (ADA).

As we age, the outer layer of tooth enamel wears away, eventually revealing a darker or yellow shade.  The color of our teeth also comes from the inside of the tooth, which can become darker over time. Smoking and fluids such as coffee, tea, and wine can also contribute to tooth discoloration, making teeth yellow and dull.  Sometimes, teeth can become discolored from taking certain medications as a child, such as tetracycline.  Excessive fluoridation (fluorosis) during tooth development can also cause teeth to become discolored.

It’s important to have your teeth evaluated by your dentist to determine if you’re a good candidate for bleaching.  Occasionally, tetracycline and fluorosis stains are difficult to bleach and your dentist may offer other options, such as veneers or crowns to cover up such stains.  Since teeth whitening only works on natural tooth enamel, it is also important to evaluate any old fillings, crowns, etc. before bleaching begins.  Once the bleaching is done, your dentist can match the new restorations to the shade of the newly whitened teeth.

Since teeth whitening is not permanent, a touch-up may be needed every several years to keep your smile looking bright.

The most widely used professional teeth whitening systems:

Home teeth whitening systems: At-home products usually come in a gel form that is placed in a custom-fitted mouthguard (tray), created from a mold of your teeth.  The trays are worn either twice a day for approximately 30 minutes, or overnight while you sleep.  It usually takes several weeks to achieve the desired results depending on the degree of staining and the desired level of whitening.

In office teeth whitening: This treatment is done in the dental office and you will see results immediately.  It may require more than one visit with each visit lasting 30 to 60 minutes.  While your gums are protected, a bleaching solution is applied to the teeth.  A special light may be used to enhance the action of the agent while the teeth are whitened.

Some patients may experience tooth sensitivity after having their teeth whitened.  This sensation is temporary and subsides shortly after you complete the bleaching process, usually within a few days to one week.

Teeth whitening can be very effective and can give you a brighter, whiter, more confident smile!

With many state-of-the-art dental treatments and prevention options available in dentistry today, there are fewer reasons for having to extract (remove) teeth.  When something does go wrong with a tooth, we try to do everything possible to restore the tooth to its original function.  Removing a tooth is the last option because we know that removal may lead to severe and costly dental and cosmetic problems if the tooth is not replaced.

Losing a tooth can be a very traumatic experience and it’s very unfortunate when it does happen.  Injury, accident, fracture, severe dental decay, and gum disease are the major reasons for having to remove a tooth.  If teeth are lost due to injury or have to be removed, it is imperative that they be replaced to avoid cosmetic and dental problems in the future.

When a tooth is lost, the jaw bone that helped support that tooth begins to atrophy, causing the teeth on either side to shift or tip into the open space of the lost tooth.  Also, the tooth above or below the open space will start to move towards the open space because there is no opposing tooth to bite on.  These movements may create problems such as decay, gum disease, excessive wear on certain teeth, and TMJ (jaw joint) problems.  These problems and movements do not result immediately, but will eventually appear, compromising your chewing abilities, the health of your bite, and the beauty of your smile.

Options for replacement of missing teeth:

Removable bridges - This type of bridge is a good solution for replacing one or more missing teeth, especially in complex dental situations where other replacement options are not possible. They are usually made of tooth-colored, artificial teeth combined with metal clasps that hook onto adjacent natural teeth. Removable bridges are the most economical option for replacing missing teeth but might be the least aesthetically pleasing. This is because the metal clasps on the appliances are often impossible to completely conceal.

Fixed bridges - This type of bridge is generally made of porcelain or composite material and is permanently anchored (cemented) to a natural tooth adjacent to the missing tooth site.  The benefit of this type of bridge is that it is fixed (not removable), and it is very sturdy.  The disadvantage is that in order to create a fixed appliance, two healthy, natural teeth will have to be crowned (capped) to hold the bridge in place.

Dentures - This type of tooth replacement is used when most or all of the natural teeth are missing in one dental arch. Dentures are removable artificial teeth that are made to closely resemble the patient’s original teeth.  

Implants - Are a great way to replace one or more missing teeth. They can also provide great support for ill-fitting dentures.  A dental implant is an artificial root that is surgically placed into the jaw bone to replace a missing tooth. An artificial tooth is placed on the implant, giving the appearance and feel of a natural tooth. Implants are very stable, durable, and are the most aesthetically pleasing tooth replacement option.

If you are missing teeth, ask us if they need replacement and what options are available to you. Together we will select the best replacement option for your particular case. Prevention and early treatment are always less involved and less costly than delaying treatment and allowing a serious problem to develop.


We’re all at risk for having a tooth knocked out.  More than 5 million teeth are knocked out every year!  If we know how to handle this emergency situation, we might be able to save the tooth.  Teeth that are knocked out can possibly be re-implanted if we act quickly and follow these simple steps:

  1. Locate the tooth and handle it only by the crown (chewing part of the tooth), NOT by the roots.
  2. DO NOT scrub or use soap or chemicals to clean the tooth.  If it has dirt or debris on it, rinse it gently with your own saliva or whole milk.  If that is not possible, rinse it very gently with water.
  3. Get to a dentist within 30 minutes.  The longer you wait, the less chance there is for successful reimplantation.

Ways to transport the tooth

  • Try to replace the tooth back in its socket immediately.  Gently bite down on gauze, a wet tea bag or on your own teeth to keep the tooth in place.  Apply a cold compress to the mouth for pain and swelling as needed.
  • If the tooth cannot be placed back into the socket, place the tooth in a container and cover with a small amount of your saliva or whole milk.  You can also place the tooth under your tongue or between your lower lip and gums.  Keep the tooth moist at all times.  Do not transport the tooth in a tissue or cloth.
  • Consider buying a “Save-A-Tooth” storage container and keeping it as part of your home first aid kit.  The kit is available in many pharmacies and contains a travel case and fluid solution for easy tooth transport.

The sooner the tooth is replaced back into the socket, the greater the likelihood it has to survive.  So be prepared, and remember these simple steps for saving a knocked-out tooth.

You can prevent broken or knocked-out teeth by:

  • Wearing a mouthguard when playing sports
  • Always wearing your seatbelt
  • Avoiding fights
  • Avoid chewing hard items such as ice, popcorn kernels, hard breads, etc.
