Hi there,
The need to replace a second molar depends on the bite and the neighbouring teeth. Basically, if there are teeth around it then replacement would be ideal to to prevent the movement of the neighbouring teeth. Teeth tend to drift into a space if it is present.
If the opposing second molar in the other jaw is present, the lack of an opposing second molar would result in an overgrowth of the that tooth as it has no partner to bite on. This will not happen slowly, it happens over the next couple of years. If the wisdom tooth/third molar is present behind the second molar, it may tip forward into the space of the second molar and result in an area which is difficult to clean. In these situations, replacing of the extracted tooth would be ideal.
There are other factors to consider as well, with regards to the dental implant. There needs to be sufficient bone in the region in order to place a dental implant. If the bone levels are not ideal or insufficient, you may need an additional bone grafting procedure to ensure there is sufficient bone for implant placement. Your dentist or oral surgeon will be able to advise you better on this.
Discuss with your dentist regarding the treatment options following the removal of your second molar. I'm sure he /she will be able to assist you with making the right decision.
Hope this helps.
Warm regards,
