When one, several or all of the teeth are missing, treatment is provided by means of prosthetic devices, which are either removable (implants, dental bridges) or removable (veneers, arch dentures). These methods restore chewing function, smile aesthetics, clear pronunciation of sounds and provide different conditions for daily dental care.
When one tooth is missing, it can be replaced by a threaded implant on which an artificial crown is subsequently fixed. An alternative solution is a dental bridge. However, in this case, the adjacent teeth are polished and the interdental cleaning becomes more difficult as the teeth are connected together. Connecting the teeth into a bridge may be a rational solution if the teeth are dead, severely decayed and need to be restored in any case.
When most or all of the teeth are missing, two solutions are available: implantation and the fabrication of a removable denture. The most cost-effective, but in all respects the most uncomfortable and, therefore, the one that requires the longest adaptation after the restoration of the lost teeth, is the removable denture. The prosthetic technique is selected individually for each patient depending on their current oral condition, preferences and possibilities.
Missing teeth may be left unrestored if the remaining teeth are sufficient for food chewing, clear speech and good looks.
Technically, it is almost always possible to restore teeth, however, this largely depends on the patient’s financial means. Today, there is no reliable scientific evidence to suggest that it is necessary to have thirty-two or twenty-eight teeth all your life. How many teeth does a person need? This is a very individual question. Therefore, the first thing to do is to ask the patient how many teeth they should have in order to chew food properly, to pronounce sounds clearly and to look good. Answers vary greatly. We all have very different needs, yet there are common patterns. First of all, it depends on age. Older patients indicate that twenty teeth in a row, without gaps, facing each other (ten in each jaw) are sufficient for them. Interestingly, children also have 20 primary teeth and do not complain about the lack of teeth. But let’s consider what it means to have 20 teeth, i.e. no molars, just front teeth and canines. That is certainly enough to crush food and speak clearly (quite a few older patients say that even fewer than 20 are enough for them), though not everybody will enjoy the fact that the end of the teeth row, i.e. the black gaps at the corners of the mouth, will be visible when speaking or smiling. This means that for the sake of aesthetics and good looks, at least one more molar tooth is needed. That said, most people consider that the minimum number of teeth to meet the needs of chewing, sound pronunciation and aesthetics is twenty-four (with teeth on each side of the jaw up to and including the first molar). One way to restore all the missing teeth is the All-on-4 technique.
