Most children's permanent teeth erupt on a fairly predictable schedule. Sometimes, though, one or more teeth might not develop as they should — or at all.

These absent teeth pose functional problems for chewing and hygiene, which can affect long-term dental health. But they can also have a disruptive effect on an otherwise attractive smile if the missing teeth are the upper lateral incisors in the most visible part of the smile.

You normally find this pair of teeth on either side of the upper central incisors (the two front-most teeth). On the other side of the lateral incisors are the canine or eye teeth, known for their pointed appearance. Without the lateral incisors, the canines tend to drift into the space next to the central incisors. This can produce an odd appearance even a layperson will notice: only four teeth where there should be six!

It's possible to correct this abnormality, but it will take time and expense. The first step is usually to move the teeth in the upper jaw with braces to their correct position. This puts teeth where they should be and also opens space between the canines and central incisors so we can eventually replace the missing teeth with dental implants.

But the key to all this is timing. It's usually appropriate to undertake tooth movement with braces during late childhood or adolescence. But implants shouldn't be installed until the person's jaw fully matures, usually in early adulthood. An implant placed before then could eventually become misaligned.

To accommodate the time between bite correction and implant placement, the patient can wear a retainer appliance that will keep the newly created space open. We can also attach artificial teeth to the retainer to camouflage the empty space.

It usually takes a team of a family dentist, an orthodontist and a surgeon to see this kind of “smile makeover” project through, possibly over several years. But the gains in better aesthetics and health are well worth the time and expense.

Dr. Richard Lee-Shanok understands the difficulty that some teenagers and adults have with their crooked teeth. They want to have a invisalignbeautiful smile but want to avoid getting braces. That's why he provides his patients with Invisalign treatment in his Newmarket, ON, office.

What is Invisalign Treatment?

Invisalign treatment consists of clear aligner trays made of plastic that are worn by patients. The custom-made aligners are made using 3-D computer imaging technology. The plastic aligners are also transparent and shift the teeth into place by applying pressure on each of them until they are straight or in the desired position.

Each set of trays needs to be worn for at least 22 hours a day. You can remove them to brush and floss your teeth, or while you're eating and drinking. If you want to take them off for a special occasion, like a wedding, you can do so, but remember, the longer they are not worn, the longer the treatment will be delayed. Also, because they are transparent, it isn't necessary to take them off. So there's no need to worry about them appearing in pictures.

The treatment can last approximately 9 - 15 months, while the average number of trays you may use may be around 18 - 30. How long your treatment will take will depend on your initial examination and the treatment plan you and your Newmarket dentist have agreed upon.

During your Invisalign treatment, you will need to see your doctor once every six weeks. He will want to make sure that your teeth are being straightened according to plan and will assess if any changes need to be made according to your progress.

If you're a teenager or adult who needs their teeth straightened but would like to avoid traditional metal braces, then you need to contact your Newmarket, ON, dentist, Dr. Richard Lee-Shanok. He will help determine if you are a good candidate for Invisalign treatment and get you started on the right path. Just call him at (905) 830-1010 to make an appointment today!

So, you’ve just acquired an attractive restoration with dental implants. You may be thinking at least with these teeth you won’t have to worry about dental disease.

Think again. While the implants and their porcelain crowns are impervious to decay the surrounding gums and bone are still vulnerable to infection. In fact, you could be at risk for a specific type of periodontal (gum) disease called peri-implantitis (inflammation around the implant).

Bacterial plaque, the thin bio-film most responsible for gum disease, can build up on implant crowns just as it does on natural tooth surfaces. If it isn’t removed with daily brushing and flossing and regular dental cleanings the bacteria can trigger an infection in the gums.

Besides weakening gum tissues, gum disease can also cause bone loss, of critical importance to dental implants. An implant depends on the bone they’re inserted in to hold them in place. If the bone around an implant becomes infected it could begin to be lost or dissolve (resorb), which could lead to loss of the implant.

That’s why it’s critical to keep the natural tissue structures supporting your implants infection-free. Not only is daily hygiene a must, but your implants and any remaining natural teeth should undergo professional cleaning at least twice a year or more if your dentist recommends it.

Cleanings involving implants will also be a bit different from natural teeth. While the dental materials used in the crown and implant post are quite durable, regular cleaning instruments can scratch them. Although tiny, these scratches can become hiding places for bacteria and increase your risk of infection.

To avoid this, your hygienist will use instruments (known as scalers and curettes) usually made of plastics or resins rather than metal. The hygienist may still use metal instruments on your remaining natural teeth because their enamel can tolerate metal without becoming scratched creating a smoother surface.

While keeping implants clean can sometimes be a challenge, it’s not impossible. Implants on average have a long-term success rate above 95%. With both you and your dentist caring and maintaining these state-of-the-art restorations, you may be able to enjoy them for decades.
