Missing a tooth or a number of them can significantly change our everyday lifestyle, particularly on the way we look and speak to others. Moreover, it can seriously affect our overall health, both adversely and in the long term. Adverse health issue includes proper chewing or eating function which can lead to indigestion. Long term health issues include bone loss and facial structure collapse.
What happens if missing teeth are not replaced?
The possible consequences would include:
What are my options for replacing missing tooth/teeth?
There are three main options, namely:
What are DENTURES?
Dentures are removable appliances with artificial teeth. There are basically two types of dentures:
Partial Dentures – if you have lost some of your teeth only. They usually come with visible metal hooks wrapped around surrounding teeth for stability and retention
Complete Dentures – if you have lost all your upper or lower teeth. They are made of wholly plastic or a combination of plastic and cobalt chromium, a form of metal.

You need to remove the dentures daily for cleaning and they should not be worn during sleep. They may move during eating especially for complete lower dentures because they rest on a smaller surface of bone, thus making retention of the dentures problematic. Upper dentures also tend to interfere with speech. It may take a while to get used to them. Dentures also tend to accelerate bone loss which make denture-wearing more uncomfortable in later years.
In addition, dentures need to be adjusted and re-aligned periodically and replaced every 3-5 years.

What are DENTAL BRIDGES?
A dental bridge is essentially made of several artificial teeth joined together to replace missing ones. Your dentist has to make permanent changes by grinding the adjacent healthy teeth to place a dental bridge. This may compromise the life expectancy of these teeth but is necessary to create space to support the bridge which is essentially several artificial teeth joined together to replace the missing ones.
Dental bridges are usually made of porcelain and gold and held onto the supporting teeth by dental cement. Through time, the cement may deteriorate allowing bacteria to attack the underlying teeth thereby causing dental decay and increasing the risk of additional tooth loss. Gum tissues also tend to shrink over time exposing the junctions between the bridges and supporting teeth.
A dental bridge needs to be replaced about every five to ten years due to wear and leakage.

Figure 5: The gums have receded and exposed the junction between a ten-year old bridge and the underlying teeth, making it unsightly. Leakage has also set in and caused decay.
What are DENTAL IMPLANTS?
Dental implants are root-like structures made of titanium, a material which our body easily accepts. They come in all shapes and sizes.
They can be used to replace as few as one tooth or all the teeth in the mouth. Other applications include replacing missing eyes, ears, noses and fingers.
How do DENTAL IMPLANTS work?
Implants are artificial roots which are inserted into the bone to replace the natural roots you have lost. A strong bond is formed between the implants and the bone over several weeks or months. The implants provide a stable foundation for crowns, bridges or dentures which are placed over them. An abutment is the interface that connects the new tooth to the implant.
Due to the extreme stability of the implants, the new teeth are very firm and make eating and chewing feel as natural and comfortable as your original teeth. They can also be made to look very real too. Implants also slow down none loss.

How many teeth can DENTAL IMPLANTS replace?
Implants can be used in all kind of situations even if you have lost:
What is the track record of DENTAL IMPLANTS over the long term?
Dental Implants have been scientifically tested and documented for over forty years. The long term success rate is as high as 95%.
What are the advantages of DENTAL IMPLANTS treatment?
It is an advanced treatment that most closely mimics the natural teeth in look, feel, and function - such as in speech and chewing.
