Sweet Air Sedation

Nitrous Oxide Gas, often referred to as laughing gas or sweet air, is a safe and effective anesthetic drug with many benefits for patients.

In 1844, a young Connecticut dentist named Dr. Horace Wells saw a public demonstration of nitrous oxide and realized the possibility of using it for dental treatment. Dr. Wells had a colleague extract his own infected tooth under the influence of the gas and continued to use it for patient treatment thereafter.

The benefits of nitrous oxide are many, and the risks are few. The gas is administered with a comfortable mask placed over the nose. The patient begins to feel a pleasant level of sedation in three or four minutes.

After the gas is adjusted to the appropriate dose, the dentist can comfortably give the injection (if needed) to the patient, and then proceed with dental treatment. After the treatment is completed, the patient is given pure oxygen to breathe for about five minutes, and all the effects of sedation are reversed. Unlike IV sedation or general anesthesia, the patients can almost always leave the office by themselves.

I use nitrous oxide frequently in my practice. I find it especially useful for fearful patients as well as young children.. A patient that was anxious just a minute or two before treatment will become relaxed and calm.

Teeth Whitening

Having white teeth helps you make a good impression, and is important for your self-esteem. Many things we do on a regular basis can contribute to stained teeth, such as drinking coffee, tea, cola and red wine or smoking.

We use a bleaching process that removes discoloration from your teeth. The procedure involves covering the teeth with a hydrogen peroxide-based whitening gel. You place the gel in thin custom trays and wear them over-night.

As the Hydrogen Peroxide is broken down, oxygen enters the enamel and dentin, bleaching the surface of your teeth while leaving the structure of the teeth unchanged.

While no dental procedure is 100% comfortable, we go to great lengths to minimize any discomfort you might feel.
