If you are missing a number of adjacent teeth, they may either be replaced with individual implants (one for each missing tooth), or by joining two or more implants together. This latter option can make implant treatment more affordable when patients are missing many teeth.
The importance of replacing missing back teeth (your molar teeth) cannot be over-emphasised, as these are the large multi-rooted teeth that are designed to do the main work of chewing your food. They are your grinding and crunching teeth – the power-houses of your bite.
When molar teeth have been lost, all of this chewing workload gets transferred to the single-rooted teeth at the front of your mouth (your food has to be chewed by something!). These front teeth are simply not designed to grind and crunch food in the way your molar teeth are, and these excess stresses on your front teeth will inevitably cause damage in the long term.
