If you’re missing a tooth, you have two options: replace it or don’t.
If you don’t replace your tooth, you face all kinds of complications
with your diet and appearance, and recent studies show that a missing
tooth greatly increases your chances of losing more teeth. There are
several options available for replacing a missing tooth. Research shows
that dental implants are the only sure way to prevent jawbone deterioration and additional tooth loss.
Why should I replace a missing tooth?
A tooth has two parts: the crown and the root. When a tooth falls out,
the section of the jaw that supported the tooth has no purpose, so it
withers and atrophies. Your remaining teeth are then supported by a
weakened jaw. A missing tooth also increases the workload of remaining
teeth, and to balance the load, teeth shift, which can cause spaces
between teeth, food impaction, and tooth decay. After about four to
eight years, remaining teeth will begin to fall out as well. Up to 19%
of adjacent teeth are lost as the result of a missing tooth. That’s five
more lost teeth if you started with a full set!
What are my replacement options?
The most popular options are partials, bridges, or implants. Let’s review them.
Removable partials have clasps that attach to surrounding
“abutment” teeth, which must carry the weight of the replacement.
Because the missing tooth's root is not replaced, the jawbone begins to
atrophy. Some people with removable partials complain of discomfort and
increased tooth sensitivity. A study conducted by the American Dental Association (ADA)
shows that removable partials actually cause patients to lose up to 30%
more teeth. This option is popular because it is the least expensive,
but in the long run, patients may actually have to spend more time and
money to replace additional teeth.
Fixed bridges require reduction of abutment teeth, so that
they can be fitted with caps. The replacement tooth is secured to the
caps and literally bridges the gap between the abutment teeth. As with a
partial, the missing tooth's root is not replaced, so the jawbone
begins to atrophy. Bridges usually last about 10 years. After this time,
surrounding teeth can begin to decay and may require root canal
therapy. According to the ADA, patients with fixed bridges lose up to
10% of their remaining teeth.
Dental implants are the ideal tooth-replacement option, because they replace the missing tooth's root as well as the crown. Dental implants
do not require support from adjacent teeth, and they keep the jawbone
strong because it has a purpose – to support the tooth's root. With dental implants, patients do not experience increased tooth decay or sensitivity as with bridges. Dental implants have a success rate of 95 to 98%, and can also secure dentures, partials, or bridgework. With regular oral hygiene, dental implants last most people for a lifetime.
To receive dental implants, you must be in good health
and have adequate bone structure. Minor pre-operatory procedures like
bone and sinus grafts may be necessary to prepare you for implant surgery. For patients who cannot withstand traditional implants, mini dental implants provide a viable alternative. Your dentist will evaluate your specific case to determine which tooth option is right for your unique case.
