Am I eligible for Invisalign treatment?

The vast majority of patients are eligible, even in severe cases requiring the extraction of multiple teeth.



Will my workplace insurance cover Invisalign?

Yes, as long as your insurance covers traditional braces.



Why do I need to wear a retainer after Invisalign / orthodontic treatment?


Teeth always re-bounce towards their original position after orthodontic treatment. This can be prevented by wearing retainers. Retainers needs to be worn indefinitely for all cases.


How do I clean my Invisalign aligners and retainers?


Soak the aligner/retainer for 30 minutes in one of the following products: hydrogen peroxide, polident or  white vinegar. Rinse the aligner/retainer with water before using them again. Aligners and retainers should be cleaned every day.



How often should I replace my Vivera retainers?

For patients who wear their retainers every night, it is recommended to replace them every 6 months. For those who wear their retainers every other night, replace them every 9 months.


What are occlusal enamel pearls?


​They are small , hard, round bumps occasionally found on the bite surfaces of a tooth, as shown on the lower left side photo. Severe toothache and root canal treatment may be necessary when the bumps are broken by normal chewing activity. The best solution to this problem is early detection around 10-12 years of age and early intervention by adding protective tooth-colored filling material around them.

Why should impacted wisdom teeth be removed?


1. Damage to other teeth: Impacted teeth often grow forward and push against the adjacent second molar. This can result in root absorption of the second molar.


2. Pathology: All teeth develop in a sac called a tooth follicle, which disappears after the tooth erupts normally. If the tooth is impacted, the sac can fill with fluid and enlarge to form a cyst. The cyst, in turn, can cause destruction of surrounding bone and/or teeth. 


3. Decay: Tooth decay easily occurs on partially impacted wisdom teeth, and since such cavities cannot be filled, severe pain may occur when the pulp of the tooth gets infected. This may be followed by the formation of an abscess. 


4. Gum Infection: Deep soft tissue pockets surrounding the impacted wisdom tooth present an ideal collecting site for food debris and bacteria, which can cause mild to severe infection of the gum from time to time. 


5. Crowding : Pressure from wisdom teeth also contribute to crowding of the front teeth. This is why some orthodontists do not consider orthodontic treatment complete until third molars have been removed.

Frequently Asked Questions

BEFORE TREATMENT

What is done during the surgical phase of implant treatment?


The gum tissue is opened, precise holes are drilled into the jaw bone and implants are placed. Sometimes, a CBCT scan is required before treatment. Some implants require second stage surgeries to uncover the implant. Overlying tissues are opened at an appropriate time and, if it is stable, an attachment is connected to the implant. After the soft tissue has healed, a crown will be placed on the implant. 


How long is the waiting time after implant surgery?


The healing phase typically lasts between 2-6 months (or more when bone grafts or sinus elevation grafts are concerned). Touch and pressure on the implant region should be minimized during the healing phase. Dentures or partial dentures that place pressure on the implant should be avoided for 1-2 weeks following surgery (or more) unless instructed otherwise. 


What are the risks and complications of implant surgery?

A small number of patients do not respond successfully to implant placement. In such cases, implants may have to be removed and replaced. Because each patient's conditions are unique, including medical conditions and healing potentials, long-term success cannot be guaranteed. Complications include, but are not limited to:


-Post-surgical infection, bleeding, swelling, pain and facial discoloration

-Cracking or bruising of the corners of the mouth

-Transient but rarely permanent numbness of the jaw, lip, tongue, teeth, chin or gum. This can be due to proximity of nerves to the surgical site, though this risk is low with careful surgery, planning and assessment of the site anatomy.

-Restricted ability to open the mouth for several days.

-Jaw joint injuries or associated muscle spasm.

-Transient but rarely permanent increased tooth looseness.

-Inflammation or infection of the sinuses (where grafts or implants to the upper jaw are concerned).

​-Tooth sensitivity to hot, cold, sweet or acidic foods.

-Shrinkage of the gum upon healing resulting in elongation of some teeth and greater spaces between some teeth.

-Restricted ability to open the mouth for several days.

​-Impact on speech.

-Allergic reactions.

-Accidental swallowing of foreign matter.


The exact duration of any complications cannot be determined and may be irreversible. There is no method that will accurately predict or evaluate how the gum and bone will heal. 


What are the alternatives to implant treatment?


1. No treatment.

2. Removable appliances, including full and partial dentures. 

​3. Fixed dental bridges.



How to care for implant?


1. Continue to see your regular dentist and hygienist.

2. Implants, natural teeth and appliances must be maintained daily in clean and hygienic manner.

3. Implants and appliances should be examined by your dentist periodically (approximately every 6 months).

4. Smoking and alcohol intake may adversely affect gum healing and limit the successful outcome of implant surgery.




When should I seek medical attention after Botox treatment?


Seek medical attention if you notice the following effects after botox treatment:


1. Difficulty swallowing (dysphagia).

2. Difficulty speaking (dysphonia).

3. Difficulty breathing (dyspnea).

4. Weakness.


These effects may occur as early as one day and as late as several weeks after treatment.


When will I see the effects of Botox treatment?


You will begin noticing an effect 2-3 days after treatment. Maximal effect occurs around 2 weeks after treatment.


How long will the results of Botox treatment last?


The results will last 3-4 months.





Will Invisalign take a longer time to finish than traditional braces?

The answer is no.  As a matter of fact,  Invisalign patients usually take about 2-6 month less to finish their treatment than regular braces users.


What are  the advantages of Invisalign compared to traditional braces?


As the name implies, Invisalign aligners are just about invisible. They are easy and comfortable to wear. Furthermore, there are no diet restrictions or changes to your dental hygiene routine. In most cases, the treatment period is shorter.


What are the disadvantages of Invisalign?

Invisalign aligners must be worn for 20-22 hours every day. The patient's compliance to this schedule is necessary for the treatment to be effective. This could be a concern for some patients - especially teenagers.


What are the risks of Invisalign / orthodontic treatment?


1. Gum problems--- Gum swelling and/or bleeding can occur during orthodontic treatment if oral hygiene is neglected. Continual poor oral hygiene may lead to early termination of treatment to prevent the development of gum disease.


2. Decalcification--- Tooth decay and permanent markings on the teeth can occur during orthodontic treatment if oral hygiene is neglected. This is mainly caused by foods containing excessive sugar and/or not brushing teeth frequently and properly.


3. Root resorption--- In a minority of patients, the tips of the roots of the teeth may be blunted or shortened during treatment. Shortened roots are generally of no disadvantage, unless gum disease develops in later life.


4. Devitalization--- In very rare instances, the tooth might become non-vital and require additional dental treatment. such as endodontic and/or veneers or crowns. 

How much will it cost to have a wisdom tooth removed?

Simple extractions cost only $169 dollars while the fee for the most complicated impacted wisdom tooth removal is $556.


How much does Invisalign cost?

As with most dental procedures, the actual cost of Invisalign treatment varies depending on the complexity  of  each individual case. The fees we charge at Summerville Dental range from $3500 to $7500,  which is about the same level we charge for regular braces. We do not charge extra fees for Invisalign patients even though the laboratory expenses to have the aligners made by Aligntech runs between $700 to $2400 Canadian dollars.

What is an impacted wisdom tooth?


An impacted tooth is one which has been prevented from erupting into the mouth. The tooth may be blocked by another tooth, dense bone or a pathological condition.  The most commonly impacted teeth are third molars or "wisdom teeth" as people call them.

When is the best time to have wisdom teeth removed?


The best time to remove wisdom teeth is between 18-22 years old. At this stage, the roots are usually not fully formed and the bone is less dense. Therefore, the wisdom teeth are easier to remove, the healing process is generally faster and fewer complications will develop. Dr. Ren highly recommends patients to remove all troublesome wisdom teeth before the age of 25.


What should I expect after wisdom tooth surgery?


1. Swelling--- Swelling after surgery is normal. You should expect to experience the most swelling 36-48 hours after surgery. After this time, the swelling begins to dissipate and subside.


2. Bleeding---  The active bleeding should have stopped by the time you leave the office. You may have a little oozing from the surgical site on the day of the surgery. This usually stops by the following morning. 


3. Bruising--- Some people may experience  bruising after wisdom teeth surgery. Most commonly it occurs at the side of the face and at corners of the lower lip. This will heal gradually and should not alarm you.


4. Stiffness--- Stiffness of the jaw could also happen after wisdom teeth surgery. This is either due to muscle fatigue after opening your mouth for a long period or due to mild inflammatory processes at the local anaesthetic injection site.


5. Sensitivity--- Sensitivity in the front of the wisdom teeth is normal and may last a few days to a week. 


6. Numbness--- It is not unusual to experience a temporary numbness of the lower lip, chin and/or tongue after wisdom teeth are removed. This occurs from pressure being placed on the nerve from swelling or the manipulation of the tooth. It is usually temporary, lasting a few days or weeks or months. In very rare cases, about 0.1-0.5% of the wisdom tooth extraction cases, this numbness could be permanent.




What are the possible complications or risks of wisdom tooth surgery?


Every operation carries some degree of risk. This risk can be minimized by careful preparative assessment of your physical condition and careful preparation of instruments. The most commonly encountered complications are discussed below.


​​1. Dry Socket--- A condition known as "dry socket" occurs in approximately 5-10% of patients. It is more common in smokers and female patients taking oral contraceptives. Dry socket is a dull throbbing pain, which starts within three to five days after the operation, accompanied by a bad taste and odor in the mouth. It is treated by cleaning and packing the area with medication that will relieve the pain. Healing is slightly slower than normal and a depression or hole may exist where things will get caught. If this occurs, you will be given a special irrigating syringe to use on a daily basis to keep this area clean until the hole fills in.


2. Nerve Damage--- The roots of lower impacted teeth often rest on and around the main nerve of the lower jaw, which provides feeling in the lower lip and chin. Very rarely, in spite of all precautions, this nerve is bruised or cut during the removal of lower third molars. The result will be numbness of the lower lip, chin, gum tissue, tongue and teeth on the involved side. This effect does not last longer than a few weeks in most cases. It improves as the nerve repairs and regenerates itself. Occasionally, the numbness may last as long as several months.  In very rare cases, about 0.1-0.5% of all wisdom tooth extractions, permanent numbness can occur. Fortunately, it occurs so rarely that its incidence is not known. After more 10,000 wisdom teeth extractions during Dr. Ren’s 25 years practice, he has only had 3 patients experience temporary numbness.


3. Damage to Adjacent Teeth, Fillings or Crowns--- Occasionally, large fillings or a crown of an adjacent tooth may be loosened, cracked or dislodged during the removal of the wisdom teeth, in spite of diligent care and skill used.  The root of an adjacent tooth may also be damaged or fractured. This happens very infrequently and is not always predictable in advance.​


4. Fractured Roots--- On removing any tooth, a portion of its root may fracture off. The surgeon will make a decision as to whether it will be necessary to remove it. In some circumstances it may be prudent to leave it. The bone and gum will usually heal over it and it seldom causes any problem.
