Step 1 - Place bristles along the gum line at a 45 degree angle. Gently brush using a circular motion along the outer and inner tooth surfaces.
Step 2 - Brush each tooth individually. Tilt brush vertically behind the front teeth. Using the front half of the brush, use the same circular motion.
Step 3 - Place the brush against the biting surface of the teeth and use a gentle back-and-forth motion. Brush the tongue to remove odor-producing bacteria.

Break off about 18 inches of floss and wind some of it around your middle finger (3 turns). This finger will take up the floss as it becomes dirty. Shorten the length between the two fingers to 6 inches and wind some floss (1 turn) around the opposite middle finger. Hold the floss tightly between your thumbs and index fingers.


Guide the floss between your teeth using a gentle rubbing motion. When the floss reaches the gum line, curve it into a C shape against one tooth. Gently slide it into the space between the gum and the tooth. Hold the floss tightly against the tooth as you gently rub the side of the tooth with an up and down motion. Before retrieving it, clean the adjacent tooth surface.


As you finish cleaning each contact wind the dirty floss once around the first middle finger and slide more new length of floss to proceed to the next contact.

What causes tooth decay? - Fair Oaks Dentist, Carmichael Dentist Dr. Chris Nhan

Tooth decay is caused by acids which are produced by bacteria in the presence of sugar. To prevent decay these bacteria, sugar and acids must be periodically removed by way of brushing and flossing.



New patients receive a comprehensive examination which includes a screening for oral cancer, gum and bone disease, blood pressure, and systemic disorders. A routine oral exam is performed on established patients to determine any changes in dental and health status since the previous visit.


Your gum tissue is measured with a fine instrument ruler to calibrate in millimeters pocket depth between the tooth and the connective gum tissue around the tooth. Pocket depths more than 4 millimeters, could indicate disease and infection. The deeper the pocket, the greater the extent plaque bacteria collects and infection in gum disease develop.


X-rays are taken as needed.


Tooth scaling and root planing occur as needed.


Routine cleanings also include a professional polishing (Prophy) that removes only the soft sticky plaque that is above the gum line.

Plaque - Fair Oaks Dentist, Carmichael Dentist Dr. Chris Nhan

Plaque is essentially the start of gum disease problems. Plaque is a build-up of particles from the foods you eat every day.


Once sugars are introduced to plaque, it turns into a tooth eating acid that sits just above the gum line. If regular oral care isn't standard, the acid will start eating at the teeth and gums.


Plaque that is allowed to sit for a prolonged period of time can cause cavities, gingivitis, and other problems in your mouth. If it's left longer than that, serious dental procedures may be required to restore your decaying smile.



After scaling the tooth roots may need to be planed to smooth the root surface. Soft tissue will re-attach itself to a smooth tooth surface.


Your dentist may also recommend medications to help control infection, pain, or to encourage healing.

Tooth scaling removes plaque, tartar and hard crusty calculus deposits, which are loaded with bacteria.


Sub-gingival tooth scaling is necessary when plaque and tartar are detected below the gum line.

Sealants - Fair Oaks Dentist, Carmichael Dentist Dr. Chris Nhan

Sealants are a proven way to help prevent cavities. Although sealants do not take the place of proper oral hygiene, they do prevent bacteria from getting into the deeper crevices in a tooth's biting surface and therefore keeping the tooth cavity-free.



Cavities generally develop in the "hard-to-see" places in your mouth. These are normally the places where you need to floss. When bacteria combine with food particles, they form plaque that adheres to your teeth.


As long as plaque remains on the tooth, acid produced by bacteria will eat away the tooth structure. Once through the enamel, the acid attacks the dentin, which is that part of the tooth containing sensitive nerve fibers.


If the tooth decay reaches the dentin, a filling is needed to halt the degenerative process. Otherwise, it continues at an accelerated rate becoming larger and larger.


If not detected and repaired with a filling, the decay can reach the tooth nerve and cause the need for a root canal. With the decay removed and a filling in place the tooth is restored to its original contour.



Fluoride - Fair Oaks Dentist, Carmichael Dentist Dr. Chris Nhan

Fluoride, a substance that's found naturally in water, plays an important role in healthy tooth development and cavity prevention.


Fluoride combats tooth decay in two ways:
1) It strengthens tooth enamel, a hard and shiny substance that protects the teeth, so that it can better resist the acid formed by plaque.
2) Fluoride allows teeth damaged by acid to repair, or re-mineralize, themselves.


Fluoride cannot repair cavities, but it can reverse low levels of tooth decay and thus prevent new cavities from forming.


The American Academy of Pediatrics recommends that these fluoride supplements be given daily to children between the ages of 6 months and 16 years. The dosage will change as your child grows. Only children living in non-fluoridated areas or children who drink only non-fluoridated bottled water should receive supplements.


Most children get the right amount of fluoride through a combination of fluoridated toothpaste and fluoridated water or supplements. Too much fluoride before 8 years of age can cause enamel fluorosis, a discoloration or mottling of the permanent teeth. This condition is unsightly but harmless and often can be treated with cosmetic procedures.



Oral cancer screening is a routine part of a dental examination. Regular check-ups, including an examination of the entire mouth, are essential in the early detection of cancerous and pre-cancerous conditions. You may have a very small, but dangerous, oral spot or sore and not be aware of it.

The doctor will carefully examine the inside of your mouth and tongue and in some patients may notice a flat, painless, white or red spot or a small sore. Although most of these are harmless, some are not. Harmful oral spots or sores often look identical to those that are harmless, but testing can tell them apart. If you have a sore with a likely cause, the doctor may treat it and ask you to return for re-examination.

To ensure that a spot or sore is not dangerous, the doctor may choose to perform a simple test, such as a brush test. A brush test collects cells from a suspicious lesion in the mouth. The cells are sent to a laboratory for analysis. If precancerous cells are found, the lesion can be surgically removed if necessary during a separate procedure. It's important to know that all atypical and positive results from a brush test, or other screening tests, must be confirmed by biopsy.
