I have recently lost a tooth to a failed root canal-mandibular second molar.carl e misch doesn't recommend replacing second molars,should i follow him?

Second opinion: Even though, world-renowned dental implantologist Carl E. Misch give you expert advice, but latest evidence based study concluded: " the placement of single-tooth implants in the second molar region was an effective and reliable treatment modality. Getting a second opinion helps you feel more confident about your diagnosis, treatment plan and prognosis. Hope it helps.

If you would like: If Dr Misch examined you and recommended that you do not replace your missing tooth, and you feel comfortable with the reasoning, then don't replace it. Remember that at 24 yo, your maxillary 2nd molar will probably super-erupt over time, resulting in an unbalanced occlusion, finally necessitating the extraction of that second molar, too. Ask another local dentist for their opinion.

Not necessarily: If you have an opposing upper 2nd molar that is in healthy condition, I would recommend replacing the tooth. If not replaced the upper tooth will eventually drop down and could interfere with your bite. If there is no opposing tooth there would be no need to replace it

Depends: replacing a lower second molar depends on several factors. The occlusion is the main factor. If the upper second molar occluded with the lower second molar only, not replacing the lower molar will result in extrusion of the upper molar long term. Hence at your young age, I would get evaluated for a possible implant! In an older patient I may not replace,so several factors come into play.

Varying opinions: Replacing a second molar often depends upon your bite (occlusion,) the opposing tooth- if present, and the condition of your dentition as a whole. I agree that age can make a difference, but I would personally get more than one opinion with options.

No: As an Orthodontist I have seen many patients who had a second molar removed and not replaced. As a result the opposing second miler super-erupted, creating interferences. Please have your Dentist evaluate your occlusal pattern and make recommendation applicable to you, rather than taking "general" advice.

Maybe: There have been several developments in implants that allow better restoration of 2nd molars. It is not a critical tooth. many people function without a second molar. It depends on how much you miss it. It is a more difficult implant to place (limited opening in back) and it will take more force than farther forward, leaving a less predictable result. Is there an opposing tooth?
