Dentures

Even though complete or partial dentures are not the ideal treatment to replace missing teeth (Dental implant supported restorations are), they can provide many people with a very acceptable restoration that will last and function for many years.

Complete dentures are used when all the teeth have been lost in either your upper or lower arch. They allow you to smile, speak and masticate (a big word that means “chew”) your food so you maintain proper nutrition. While not the ideal restoration these days, they are necessary and will allow you to function far better than if you didn’t replace your missing teeth and had to mash up all your food.

One version of a complete denture is called an IMMEDIATE DENTURE. An immediate denture is a complete denture that is placed at the same time as your last remaining tooth is removed. It allows you to instantly have a full set of teeth and walk out of the office wearing your new denture.

Another version of a complete denture is called an OVERDENTURE. An overdenture is a complete denture that is partially supported by some remaining roots or implants. These roots or implants usually have some type of attachment that allows an insert placed in the denture to snap the overdenture in place. Overdentures are a very effective form of complete denture therapy and far more desirable than a normal complete denture.

A PARTIAL DENTURE is a tooth replacement appliance that replaces one or more missing teeth. It is held on by ‘clipping’ on to some of your existing natural teeth or crowns. They are two types of partial dentures- conventional and precision.

A CONVENTIONAL PARTIAL DENTURE is a tooth replacement appliance that stays in place by ‘hooking’ or ‘clipping’ on to some of your existing natural teeth or crowns. You can generally identify a conventional partial denture by a small metal clasp around one or more teeth.

A PRECISION PARTIAL DENTURE is a tooth replacement appliance that stays in place by attaching to one or more permanent crowns. Generally, precision partial dentures show no metal when you smile and attach to crowns using a number of different precision devices that are very long lasting.

Dental Implants

A dental implant is an artificial tooth root that a dentist places into your jaw to hold a replacement tooth or bridge. Dental implants are an ideal option if you have good general oral health and have lost a tooth or teeth due to periodontal disease, an injury, or some other reason.

While high-tech in nature, dental implants are actually more tooth-saving than traditional bridgework, since implants do not rely on neighboring teeth for support.

Dental implants are so natural-looking and feeling, you may forget you ever lost a tooth. You know that your confidence about your teeth affects how you feel about yourself, both personally and professionally. Perhaps you hide your smile because of spaces from missing teeth. Maybe your dentures don't feel secure. Perhaps you have difficulty chewing. If you are missing one or more teeth and would like to smile, speak and eat again with comfort and confidence, there is good news! Dental implants are teeth that can look and feel just like your own! Under proper conditions, such as placement by a dentist and diligent patient maintenance, implants can last a lifetime.

Crowns & Bridges

Bridges
A dental bridge is a device used to fill the space where a tooth has fallen out or been removed. A typical dental bridge consists of a pontic (a filler tooth) that is attached to two surrounding crowns (abutments). Once complete, this bridge structure is bonded into the mouth. Without the use of a bridge, spaces in the mouth from missing teeth can cause multiple teeth to shift, lead to occlusion (biting) and/or jaw problems, and may spur periodontal disease. Dental bridges safeguard the integrity of existing teeth and help maintain a healthy, vibrant smile.

Crowns
When a tooth is cracked, decayed, or damaged, a dental crown may need to be fitted onto the tooth. A dental crown is a permanent covering that fits over the original tooth. Crowns can be made of porcelain, gold and other metals, acrylic resin, or an amalgam (a mix) of these materials. Porcelain crowns typically have the most realistic appearance, although they tend to be less durable than other materials. Dental crowns can whiten, reshape, and realign existing teeth, adding to a healthy and vibrant smile.

How many teeth should an adult have?

A:

Thank you for your question Anthony. This is a question I am asked quite frequently from both adults and children alike.
An adult who has his/her full set of teeth, including their wisdom teeth should have 32 teeth. Exceptions can always occur though, some people these days do not form all four wisdom teeth thus they may have less than 32 teeth. As well, occasionally a person may either be missing a tooth (it does not form) or form an extra tooth, these are exceptions to the rule.

Frequently Asked Questions

Q:Which type of toothbrush should I use?

A:The brand of the toothbrush is not as critical as the type of bristle and the size of the head. A soft toothbrush with a small head is recommended because medium and hard brushes tend to cause irritation and contribute to recession of the gums, and a small head allows you to get around each tooth more completely and is less likely to injure your gums. It's unnecessary to "scrub" the teeth as long as you are brushing at least twice a day and visiting your dentist at least twice a year for cleanings.

Q:What’s the difference between a “bridge” and a “partial denture”?

A:Both bridges and partial dentures replace missing teeth. A bridge is permanently attached to abutment teeth or, in some cases, implants. A partial denture is attached by clasps to the teeth and is easily removed by the patient. Patients are usually more satisfied with bridges than with partial dentures.

Q:Do I need to have a root canal just because I have a crown?

A:No. While most teeth which have had root canal treatments do need crowns to strengthen the teeth and to return the teeth to normal form and function, not every tooth needing a crown also needs to have a root canal.

Q:Is it possible for my teeth to be more sensitive if I brush?

A:The general answer is a definitive no, if you are brushing correctly. The outside layer of your teeth is made of enamel. This is an extremely hard substance that is very wear resistant. Our suggestion though, is to always use a soft tooth brush so as not to harm the surrounding gums when you brush.

Painful new crown/cap

Q:
Via email Mon.March.1, 2010 from Anonymous.

I had a crown placed on the rear bottom tooth on the left side a couple of months ago, and when the freezing wore off after placement of the permanent crown, I was up every few hours taking painkillers - it was the worst pain I've ever had. This tooth had never bothered me in the past, but a small piece had broken off, and my dentist recommended getting a crown.

I went back several times, and he gave me prescriptions for antibiotics, painkillers, ground the tooth down, and eventually, after about 3-4 weeks, the pain subsided.

A week ago, it has started up with a vengeance. It is excruciatingly painful, will wake me up out of a sound sleep.

He never did give me a reason as to why it happened in the first place, why placing the permanent crown would cause such awful pain.

Any help you can give would be appreciated.


A:
Thank you for your question. I am sorry to hear you are in pain from your newly placed crown. A permanent crown can give discomfort for a few reasons.

Sometimes after initial preparation and placement of a new crown the nerve can flare up and cause discomfort in the tooth. This will typically settle down with time. If it doesn't then the new crown may be 'high' and need adjustment (ie. grinding the crown down a little) so it doesn't meet with the opposing teeth in an irregular manner. When a tooth is high it can aggravate the nerve and cause discomfort, almost how a bad bruise gives you discomfort, so can a irritated nerve of a tooth. This should be alleviated after adjustment (grinding of the tooth), typically it would go away within a few days.

The last reason may be that the nerve is irritated irreversibly (due to bacteria, trauma or otherwise) and thus may need a root canal (simply put the removal of the pulp) so you will not have the pain any longer.

You will need to see your dentist to assess the situation of the tooth so a solution can be found.
