There are several types of fillings, but most common are temporary, silver (amulgum) and white (resin) fillings.

Temporary fillings are done when root canal is done or we are waiting for pulp to quiet down before doing permanent filling or crown on that tooth. They are not meant to last a long time, and they usually wash off or break down within a month.

Silver fillings are made with silver, zinc and other metals. They are made of alloy material containing mercury, which some people are allergic to, and they do not match tooth color. They can withstand chewing forces and are less expensive then tooth colored (resin) fillings. Silver fillings add a grayish hue to the surrounding tooth structure.

White fillings are tooth colored fillings made of resin composite material, and they have different shades to match your natural tooth shade so it looks like a natural tooth and not a tooth with filling. White fillings require less removal of the natural tooth and are bonded onto the natural tooth. White fillings may not last as long as silver fillings.


A full crown covers the whole tooth. Crowns usually require two visits to complete. They are made of porcelain, high-noble metal, or gold. Crowns are usually done after a root canal procedure on a tooth, to cover a large decayed area or broken tooth. They are very durable and last a long time.

¾ crowns covers ¾ of the tooth. They are bonded onto the tooth.

Root Canals

When a tooth is badly decayed or infected, a root canal procedure is performed to save the tooth. During this procedure nerve and infected pulp is removed. The inside of the tooth is cleaned and sealed. Most likely you will need a build up and crown after a root canal procedure if the large part of the tooth is removed during the procedure.


Veneers are made of porcelain material or resin composite materials. They are very thin and cover the front of the tooth. They are added for cosmetic reasons to improve color, shape, size or length of the natural tooth. They are bonded onto the natural tooth and require less removal of tooth surface. Some insurance may not cover Veneers or provide alternate benefits of less expensive procedure.


Implants are replacement of dental roots. They are made of titanium. The implant is placed during the first visit. The second visit follows up with abutment placement and impression for implant crown, bridge, partial, or denture. At the third visit implant crown, bridge, partial, or denture is placed. Implants feels more like natural teeth, and they are more permanent solutions than than bridge/partials or dentures. Implants are very durable and last a long time; with proper care they may last a lifetime. They are better choice for oral health and good hygiene.

Periodontal (GUM) disease: Causes Symptoms and Treatments

Our mouths are full of bacteria. These bacteria, along with mucus and other particles, constantly form a sticky, colorless plaque on teeth. Brushing and flossing help get rid of plaque. Plaque that is not removed can harden and form bacteria harboring tarter that brushing cannot remove.

Gingivitis — The longer plaque and tarter are on teeth, the more harmful they become. The bacteria causes inflammation of the gums that is called “gingivitis”. With gingivitis, the gums become red, swollen and can bleed easily.

Periodontitis — When gingivitis is not treated, it can advance to “Periodontitis” (which means “inflammation around the teeth and infection of ligaments and bone"). In periodontitis, gums pull away form the teeth and form pockets that are infected. Bacterial toxins and the body’s enzymes fighting the infection actually start to breakdown the bone and connective tissue that hold teeth in place.

Risk Factors: Smoking, hormonal changes in girls/women, diabetes, stress, medications (antidepressants and some heart medications), Illness (aids) and genetic susceptibility.

People usually don’t show signs of gum disease until they are in their 30s and 40s. Men are more likely to have periodontal disease then women.

To prevent gum disease:

  • Brush your teeth twice a day (with fluoride toothpaste)
  • Floss everyday
  • Visit the dentist routinely for a check-up and professional cleaning
  • Eat a well balanced diet
  • Don’t use tobacco products

Tooth Whitening (Bleaching)

Everybody loves a bright white smile and there are a variety of products and procedures available to help you improve the look of yours.

You can take several approaches to whiten your smile:

  • in-office bleaching
  • at-home bleaching
  • whitening toothpastes

Dentist in-office power bleaching

The in-office power bleaching is one of the quickest and most effective ways to whiten teeth but requires a session at the dentist’s office. The dentist isolates and protects your lips, gums and inside lining of your mouth. Next, a powerful bleaching agent is applied to the teeth. Finally, a powerful light source is applied which completes the procedure by activating the bleaching agent.

Pros: fast dramatic results can be achieved. You can have immediate results for a special event. You are working with a professional who knows how to handle such ingredients and procedures and can integrate bleaching into your overall oral health care plan.

Cons: The cost is higher then at-home bleaching. Minor and transient teeth sensitivity can occur for some patients.

Dentist supervised take-home bleaching systems:

With these systems, the dentist makes a mold of your teeth. This mold is then used to create custom mouthpiece trays, which snugly fit your teeth.

The patient takes the trays and bleaching agent home.

Each night for two or three weeks the patient places the bleaching agent in the trays and places trays in his or her mouth.

The mouthpiece trays are custom made to fit each individual’s mouth. This means the bleaching agent is less likely to be swallowed or less likely to seep onto and irritate gum tissue.

For extremely yellow teeth, an in-office power bleaching is performed followed by treatment with a dentist supervised take-home system. This usually provides good results.

Orthodontic Treatments

Dr. Kermanshi provides many orthodontic treatments such as early orthodontic treatment for children, conventional and clear braces for children and adults, retainers, Invisalign® for adult, Invisalign® for teen and orthodontic treatment for patients undergoing orthognathic (jaw) surgery.

Orthodontic Treatment for Growing Children

The American Association of Orthodontists recommends all children to get a check-up with an orthodontic specialist no later than age 7. While your child’s teeth may appear to be straight, there could be a problem that only an orthodontist can detect, In addition, if you notice any of the following in your child, check with the orthodontist:

  • Cross bite of front or back teeth
  • Crowding or spacing
  • Bite problems: Protrusion, deep bite, under bite, or open bite
  • Early or late loss of baby teeth
  • Difficulty with chewing or biting
  • Speech difficulties
  • Biting the Cheeks or the roof of the mouth
  • Mouth Breathing
  • Oral habits such as sucking thumb, fingers or tongue
  • Facial imbalance

Problems to Watch for in Adults

  • Crowding or spacing
  • Anterior cross bite
  • Tooth wear/ bruxism
  • Periodontal (gum and bone) Problems
  • Impacted, tipped or missing teeth
  • Protrusion, open bite or deep bite

Correction of orthodontic problems in adults can help to prevent or improve periodontal problems and prevent or reduce further bone loss around teeth. It enhances aesthetics for a better smile & appearance, and improves self-confidence and self-esteem. It also enables the dentist to properly restore the missing teeth. Orthodontic treatment in adults helps the teeth to function better and assists the patient to maintain better oral hygiene for healthier teeth, gum and bone around the teeth.


Invisalign® is a clear alternative to braces to achieve the smile you want. Developed by an orthodontist, Invisalign is a virtually invisible solution, so you can smile both during and after the treatment. In fact, almost no one will know you are wearing them unless you tell. By using a series of clear, removable aligners that are changed every two weeks, Invisalign gradually moves your teeth toward the smile you’ve always wanted. Invisalign can help to correct a broad range of dental and orthodontic issues such as: crowding, spacing, overbite, under bite, deep bite, and open bite.

Invisalign teen is a new product that can straighten your child’s teeth
