A treatment recommendation appropriate for you and your child will be made. Any other consults that will enhance the success for you and your baby might be also be suggested during this time.

He has been asked to given his informative, spicy and edgy presentations to Bay Area Lactation Associates at El Camino Hospital in Los Gatos; The Santa Clara County Public Health Program- “Barriers to Breastfeeding” At Sutter Health Lactation/ Maternity Center in Santa Cruz, and Dr. Ligh has authored an article titled “The Team Approach to Successful Breastfeeding and Tongue/Lip Tie Release”. Dr. Ligh is also doing a monograph for the Bovie Medical Company in Clearwater, Florida: “Lingual Frenectomy with Electrocautery”.

For new parents, we follow the recommendations of the American Academy of Pediatric Dentistry – “first visit by the first birthday”. Recognizing the short attention span of 1-year-olds, we will perform an exam, demonstrate proper oral hygiene techniques, and discuss your child's eating, feeding, and oral habits with you.

It’s recommended that you bring your baby in for a visit six months after the first tooth erupts (usually around their first birthday). The earlier your child visits us, the quicker we can help you be aware of early problems with your child’s oral health, and how to best take care of your little one’s teeth. How to avoid cavities and setting a good example are important parts of your child’s health, and during our first visit we’ll discuss these techniques.

Most children sucking their thumbs or fingers from a very young age. Sucking is a natural reflex for an infant, and it serves an important purpose for that age. According to the American Dental Association, most children stop thumb sucking on their own between the ages of two to four, however some continue into their primary school years. If your child is older than four and still thumb sucking, please read this article from the ADA or request an appointment.

Injuries to mouth and teeth are common among athletes, so it’s vital to protect your child’s smile when he or she plays sports for aesthetic and health reasons. If a tooth is knocked out, chipped, cracked, or displaced due to trauma, please call our office as soon as possible. We recommend the use of a sports mouthguard while playing sports. Our doctors can recommend the best mouthguard for your child’s needs for their sport and fitment concerns.

If you or your child experiences a dental emergency, please call us immediately. If you need urgent treatment after hours, please call our emergency number. If your child experiences any of the following: bitten lip or tongue, object caught in teeth, broken chipped or cracked tooth, knocked-out tooth, loose tooth, toothache, broken jaw, or any other dental trauma, please contact us. For strategies to help in the meantime, please visit the Dental Emergency page.

Normal pits and grooves on the chewing surfaces of back teeth can trap food that can't be removed by brushing or washed out by water or saliva. A sealant is a tough material designed to bond (stick) to tooth enamel.

We do not use BIS GMA products.

Composite fillings are more than just attractive. They require minimal tooth preparation, in other words less healthy tooth structure is removed to restore the tooth. Also, a sealant can be placed over the remaining exposed grooves of the tooth to minimize the risk of decay on another area of the tooth.

Prevention is always better than treatment. Brush your teeth twice daily using any soft-bristled, ADA-approved toothbrush. We also recommend the use of modern electric tooth brushes such as Sonicare and Braun. Floss daily to remove plaque between teeth that you can't reach with regular brushing.

Always rinse thoroughly with water after brushing (or after meals if you are unable to brush). You may occasionally use a mouthwash to rinse. Children may benefit from the use of ACT fluoride rinse, to help prevent cavities from forming in between the teeth.

Dental x-rays or radiographs allow the dentist to see things about your child's oral health that cannot be seen by the naked eye. These items include cysts, cancerous and non-cancerous tumors, invisible decay that occurs between teeth, and the location of teeth that haven't grown all the way in.

Modern dental x-ray machines are very safe. We use only state-of-the-art, low radiation machines. The amount of radiation exposure your child's body receives on an airplane flight from Los Angeles to New York exceeds the amount of exposure they will receive from a modern dental x-ray machine. Contrast this minimal exposure with the risk of not finding an illness until it is too late, and you can see why we prescribe regular diagnostic x-rays.

While x-rays can provide valuable information, they don’t give a complete view of everything going on inside the mouth. With an intraoral camera, we can see every aspect of the teeth and mouth in incredible detail, and view cracked teeth, plaque deposits, cavities, and excessive wear. Both our doctors, your child and you can see everything on a monitor. It’s a great tool for us to use with you and your child to understand your child’s individual needs and treatment options.

If you have been thinking about orthodontic care for yourself or a loved one, you may be wondering: When is the right time to see an orthodontist? It’s an excellent question, and the first and most basic answer is you should see an orthodontist any time you have a question about the alignment of your teeth or the quality of your bite.

For children, the American Association of Orthodontists recommends an evaluation around the age of 7. By this age, an orthodontist can usually determine whether or not there is adequate room in the mouth to accommodate the permanent teeth. Some conditions are far easier to treat if they are caught at an early stage, when the child’s natural growth process is in full swing. For example, a palatal expander appliance can effectively correct a child’s crossbite (the upper teeth bite inside the lower teeth) because a child’s jaw is still malleable and growing. If left untreated this may be impossible to correct later on without surgery. We can also detect other problems such as early loss of baby teeth, thumb sucking, or tongue thrusting.

Keep in mind, early screening doesn’t mean treatment has to start right away. Most kids do not begin active orthodontic treatment until they are 9-14 years of age.

We look forward to meeting you at your first visit to our office. During this time we will help you get acquainted with our office and learn about your orthodontic treatment. We understand that each patient’s orthodontic treatment is different, so we try to give you the personal attention you deserve and answer as many questions as possible. Your first visit will consist of an initial examination where Dr. Kwong will evaluate if treatment is needed at this time. If treatment is needed he will discuss potential treatment options with you and the estimated length of the treatment. The treatment coordinator will discuss the estimated treatment costs and answer any financial questions you may have. Working together, we can achieve a true partnership with a common goal of helping you achieve a beautiful smile!

Invisalign® clear aligners are made of nearly invisible polyurethane plastic. They are completely removable, unlike traditional braces. They offer the advantages of improved oral hygiene, more dietary choices, esthetics, and comfort. Invisalign® applies force to the teeth much like braces, but uses plastic fabricated from a computer software program to do so. If interested, Dr. Kwong will determine if you are a candidate for Invisalign® treatment.

Traditional Metal Braces - They are made from a high-grade stainless steel and are by far the most common type of fixed orthodontic appliance. They consist of small metal brackets that are cemented to the front surfaces of the teeth. A thin wire that runs through the brackets gently guides the teeth into proper position. Metal brackets are a reliable and effective treatment option.

Ceramic Braces - These brackets are similar to the traditional metal braces but are less noticeable. They are made with a translucent ceramic material. Their esthetic appeal is undeniable, but there are a few tradeoffs. They can be less durable than metal, certain tooth movements may be less efficient, and they typically do cost more than metal brackets.

Invisalign® - Invisalign® clear aligners are made of nearly invisible polyurethane plastic. They are completely removable, unlike traditional braces. They offer the advantages of improved oral hygiene, more dietary choices, esthetics, and comfort. Invisalign® applies force to the teeth much like braces but uses plastic fabricated from a computer software program to do so. If interested, Dr. Kwong will determine if you are a candidate for Invisalign® treatment.

Phase I Treatment

The goal of first phase treatment is to save space in the dental arches for all permanent teeth to erupt and to ensure that the upper and lower jaws relate properly to each other. The type of treatment your child will need will be determined by his or her orthodontic problem. The severity of the problem will determine the type of appliances to be used and the length of time treatment will take. First phase orthodontic treatment usually takes 12-15 months. Left untreated, some conditions may not be treatable later with dental braces alone and can result in…

• Removal of permanent teeth
• Impacted teeth
• Severe displacements of teeth
• Orthodontic Jaw surgery

Phase II Treatment

Phase II treatment begins when all of the permanent teeth are present. The goal of second phase treatment is teeth straightening of all the permanent teeth and establish an optimal bite. The severity of the case and patient compliance will determine the length of orthodontic treatment. Second phase orthodontic treatments normally involve the use of dental braces and usually takes roughly 12 to 18 months.

What Do Orthodontists Do?

Orthodontists are dental specialists who diagnose and treat problems with the alignment of the teeth, and irregularities in the face and jaw. We use a number of special treatments, including braces and other appliances to correct these issues.

Why Should I, Or My Loved Ones, Get Orthodontic Treatment?

There are two good reasons: esthetics and function. Having an attractive smile not only changes the way people see you, it also enhances your self image as well. Orthodontic treatment will also allow your teeth to function better which makes it easier to chew and to keep them clean.

When Should Orthodontic Treatment Start?

You are never too old to undergo orthodontic treatment. If you start earlier, sometimes there are problems that we can correct that we cannot if you are older. The American Association of Orthodontics recommends a child see an orthodontist for an evaluation around the age of 7.

Does Getting Braces Hurt?

Having braces is generally painless. Some people experience minor aches and pains the first couple of days as they adjust to having something new in their mouths. There are many things can help alleviate the minor discomfort such as over the counter pain medication, and eating softer, colder, foods such as ice cream or smoothies.

How Long Does Treatment Last?

This is different for each person, depending on the severity of their case. Active treatment can range anywhere from 6 to 30 months, but the usual is about 24 months.

Do I Still Need to See My Dentist While In Orthodontic Treatment?

Yes, absolutely. Keeping your teeth free of plaque can be more challenging with braces on. So seeing your dentist while in braces is very important to keeping your teeth and gums healthy.

Is Orthodontic Treatment Expensive?

Orthodontic care is a long-term investment in your health and well-being. Yet it’s cost has not increased as fast as other consumer prices. We never want finances to be a barrier to getting that smile you have always wanted, so we offer many financing options that will help make care more affordable.

Having orthodontic treatment may take a little bit of time to get used to. It is common to experience soreness when appliances are first put on and some minor aches as teeth begin moving into new positions. Yet, it is comforting to know that true orthodontic emergencies are rare.

If you think you may have an emergency the first step is to determine the severity of the problem. Is it an urgent situation that requires immediate attention, or a minor problem that you can take care of yourself until you can come to our office.

A Major Emergency includes:

• Trauma or injury to the teeth or mouth
• Infection or swelling of the gums
• Severe pain of the teeth or gums

If any of these occur, the best place to start is usually with your dentist as they can most likely offer the proper diagnostic tools, anesthetics, and treatments you need. However feel free to call our office as well, if we can be of assistance.

Fortunately, the vast majority of orthodontic problems are very minor. However, they still may cause some discomfort or irritation. Some of these Minor Emergencies include:

Loose or broken brackets - this often occurs from eating hard candy or food or playing with the braces. If the bracket is still attached to the archwire, leave it as is. You can cover it with wax if it is irritating the inside of your mouth. If the bracket has come off completely, save it and bring it with you to your next appointment.

Poking archwire - as the teeth start to move, the wire connecting them can also move and poke near the back of the mouth. You can try to take the end of a pencil eraser and move the wire or use a nail clipper or wire cutter to clip the end. You can also place wax at the end of the poking wire.

General tooth soreness and looseness - it is normal for teeth to be slightly loose during orthodontic treatment, as it shows they are moving. For soreness, you can use over the counter pain reliever and eat softer foods.

Our goal is to make orthodontic treatment as comfortable as possible. If you need additional advice, do not hesitate to call us.

Retention is a critical follow-through stage that involves wearing a retainer after your active orthodontic treatment is complete. There are several types of retainers available, all of which are custom made to fit you. We will recommend the type or types that will work best in your situation. You may wonder why you have to wear a retainer. If you don’t wear one your teeth will start moving back to where they were. Teeth are not just set in the jawbone but also held in place by ligaments and fibers. It takes several months for the teeth to adjust to their new position. So it is essential to wear your retainer very well for the first several months after your braces come off. However, orthodontists typically advocate retainer wear indefinitely. This is because there is pressure from your lips, tongue, etc that are pushing on your teeth. If you stop wearing your retainer over a period of time your teeth will move. So if you want to keep that new smile and not waste all the time and effort that went into achieving it, you will want to wear your retainer.
