Invisalign Orthodontic Treatment

We love Invisalign at Upper Canada Dental, and have improved the smiles of hundreds of patients using this orthodontic treatment. Dr. Railton is a premier provider of Invisalign which is a distinction given to a dentist who has completed the necessary Invisalign courses and has done enough procedures to qualify as a premier provider for Invisalign.

Invisalign is a proprietary method of orthodontic treatment which uses a series of clear, removable teeth aligners used as an alternative to traditional metal dental braces. As of April 2008, more than 730,000 patients have completed or are currently in treatment.


The aligners are completely transparent, therefore far more difficult to detect than traditional wire and bracket braces. This makes the method particularly popular among adults and teens who want to straighten their teeth without the look of traditional metal braces, which are commonly worn by children and adolescents. In addition, the aligners are marketed as being more comfortable than braces Due to the removable nature of the device, food can be consumed without the encumbrance of metallic braces.

Clinically, aligners avoid many of the side effects of traditional fixed appliances, for example the effects on the gums and supporting tissues. Almost all other types of orthodontic treatment will cause the roots of teeth to shorten (root resorption) for most patients, and demineralization or tooth decay occurs in up to 50% of patients because (unlike Invisalign) they cannot be removed for eating and cleaning, and because they prevent accurate x-rays from being taken. Patients “graduate” to a new set of aligners in their treatment series approximately every two weeks and the average case length is typically between 6-12 months.


The aligners must be removed before eating, an advantage and disadvantage depending upon the person. They and the teeth should be cleaned before re-inserting them afterwards. The aligners should always be removed when eating, and also when drinking anything that is not water or any cold, clear, non-sugary liquids. Sugars and other debris could become caught in the aligner causing cavities and other dental problems.

Certain teeth are slightly problematic for Invisalign aligners to rotate. Some lower premolars with their rounded shape can be difficult for the aligners to grasp and apply a rotational force to, so bonded attachments made from composite material may be required.

The cost is based on the length of treatment and ranges from $2000 to $5800.

A dentist, begins by taking dental impressions, x-rays and photographs of the patient’s teeth and sending them to Align Technology. The impressions are put through a CT scan from which a computer creates a three-dimensional model. Technicians then individualize the teeth in the computer model and move them to their final position as prescribed by the orthodontist. Custom software then simulates the movement of the teeth in stages. The orthodontist reviews the simulation online using ClinCheck via a web browser and approves or modifies the treatment. This is complimentary at Upper Canada Dental ,although there is a small charge for an x-ray if one hasn’t been taken recently. Once approved, a plastic resin aligner is manufactured for each stage of the computer simulation and shipped to the dentist. Average treatment time is about one year, again depending on the complexity of the treatment. Simple treatments (minor crowding, minor spacing) may be as short as twenty weeks—this is known as the “Invisalign Express” program. Although the aligners are removable, they must be worn at least 20 to 22 hours per day to avoid delaying the treatment process. If they are not worn consistently, treatment time will increase.

Baby Teeth, a Parents Guide

Primary or “baby teeth” usually start to erupt or “come in at around 6 months of age. The anterior or “front teeth” are the first to pop through. A child’s reaction to this process can vary greatly. Restlessness, crying and red, rosy, cheeks are common and may be accompanied by a low grade fever. Chewing on a “teething ring’” may give some relief. Make sure that what they chew on is made of an “approved” material and that it is big enough to avoid choking. A chilled teething aid may prove to be even more beneficial. “Over the counter” medicines, such as “Orajel” are topical anesthetics which temporarily “numb” the sore area. These should be used sparingly and rubbed into the surrounding gum area. These teeth will continue to pop up during the first 3 years of life.

The First Visit:

A child’s first dental visit should be at around 2 years of age. This visit is kept short with a ride up and down on the dental chair and hopefully fun for the child. If anything out of the ordinary is noticed before the age of 2, definitely bring the child in for a quick look. I also recommend bringing them in as an “observer” during your adult checkup, just to get them comfortable with the office. Children are very perceptive and will pick up on your phobias. If you are a “dentalphobe” try your best not to let your child pick up on this or it will make them hesitant, especially at their first appointment. You should play their appointment up to be a fun experience, possibly with a “reward’ at the end. There are many animated “going to the dentist” books for children which can give them a “heads up” as to what to expect during the visit. Dentistry has come a long way and believe it or not, most children actually enjoy coming to the dentist.

Importance of Primary Teeth:

Primary teeth are very important and therefore, important to keep until they are replaced by permanent teeth. Five or six years of age, is when children start losing their front baby teeth. The last primaries usually last until eleven or twelve years of age. Parents will occasionally ask me whether “it is worth fixing a baby tooth”. My answer is always, “unless the tooth is soon to be lost naturally I would recommend repairing and keeping the tooth if possible.” If a primary tooth is lost prematurely, the space it was saving for the permanent tooth will be lost and the permanent tooth will be” squeezed out.” Occasionally the opposite situation arises where a primary tooth hangs on too long and won’t fall out on its own, preventing the eruption of its permanent replacement. In this case the primary tooth is removed by the dentist. Nine times out of ten the baby tooth will exfoliate or “fall out” on its own. A child’s response to the loose tooth is a very personal thing. Some are working on removing it at the first indication that it is loose. This is quite often in response to an older sibling losing their teeth or a classmate. The promise of a visit from the tooth fairy can be a big motivator. On the other hand, some children will not have any part in helping to loosen the tooth. Again, the tooth will usually fall out on its own.

Cleaning your child’s Teeth:

Due to the importance of primary teeth, keeping them clean and healthy is of the utmost importance. Cleaning should start as soon as you see a tooth emerging. This is usually a front lower tooth. The simplest technique is to wipe the teeth and gums with a clean, wet washcloth. I recommend doing this at the start of bath time. Once a tooth has erupted a small head toothbrush and dab (grain of rice size) of fluoridated toothpaste should be used. The amount of paste is important as too much fluoride can be harmful. Some parents choose to use a non-fluoridated paste until the child is able to fully rinse. Letting a child start the brushing process and the parent finishing is fine but the parent must stay in charge of placing the toothpaste on the brush to assure the correct amount is used. Once a child can tolerate and hopefully enjoy a battery powered “spin brush”, I highly recommend using one. Primary teeth are usually spaced and flossing is not necessary but where the teeth are tight and touching one another, flossing is important. Many flossing aids are available. The key to making brushing and flossing a positive experience is to keep things simple and try to add some fun to the routine.

Good luck,

Teeth Grinding

Teeth grinding or bruxism is a very common problem affecting about 25% of the general population. Most people clench and/or grind at times but not all have symptoms. The 2 most common symptoms are: jaw pain and tooth wear. Jaw pain can range from occasional headaches to chronic TMJ dysfunction. TMJ is your tempero mandibular joint or jaw joint. This habit occurs both during sleep and when awake. If you notice yourself clenching and/or grinding during waking hours, I guarantee that you are also doing it while you sleep. While awake, you can stop yourself but, while asleep this parafunction can go on unchecked.

Signs and symptoms:

The most common sign of bruxism is tooth wear. Minimal tooth wear is normal and increases with age. Tooth wear can also increase with malocclusion or an unbalanced bite. The more severe the habit the more severe the wear. Eventually, teeth will wear through the outer layer or enamel. Without this hard outer layer, the teeth wear even faster as the softer dentin layer is exposed. Another common sign is abfraction. Abfraction of a tooth is when a groove or notch forms on the tooth surface, just above the gum line. This is caused by the repeated torquing of the tooth while grinding. Symptoms of bruxism include; jaw pain, neck pain, ear pain, tinnitus, insomnia, loose teeth, and gum recession.


Stress is the main cause of bruxism. This is not to say that someone who grinds their teeth is more stressed than someone who does not, but your “normal” or “average” grinding will definitely increase with increased stress. Other things that increase your bruxing are: other sleep disorders, malocclusion, alcohol, caffeine and some medications.


The most simple and non-invasive treatment for grinding is to wear an appliance or mouth guard. This mouth guard is typically worn to bed but, can also be worn during the day at times when you notice you are grinding (while driving, working on your computer, etc.). Massage therapy can also help. Medications such as muscle relaxants may provide some relief. More severe cases with advanced TMJ dysfunction may require surgery. After your dentist has evaluated your bite and symptoms, you can determine your best treatment options.
