I completely understand your concern, especially after experiencing a failed RCT. However, a previous RCT failure does not mean that an implant will necessarily fail in the same way. A dental implant is generally a predictable option for replacing a missing molar, provided the bone and gums are healthy and the treatment is properly planned. The procedure is performed under local anaesthesia, so you should not feel pain during the placement. Some soreness or mild swelling can be expected for a few days afterward and is usually manageable with prescribed medication. Before proceeding, I would recommend a proper clinical examination and, if required, a CBCT to assess the available bone and the surrounding structures. Your dentist can then discuss the implant type, need for any bone augmentation, expected success, and the complete cost with you. Since it is an expensive treatment, there is no harm in taking a second opinion from an implantologist before making a decision. You don't need to rush into the procedure simply because the tooth has been extracted. Most importantly, try to look at the implant as a replacement for the tooth that has already been lost rather than as a continuation of the previous RCT problem. With proper planning and maintenance, implants can be a reliable long-term option.

I completely understand your concern, particularly after experiencing failure of a previous root canal treatment. However, a missing first molar at your age is something worth addressing, and a dental implant is currently one of the most predictable options for replacing a single missing tooth when the case is appropriately planned. As an Oral & Maxillofacial Surgeon with a special interest in dental implant surgery, I would recommend a thorough clinical and radiographic assessment before deciding on treatment. This includes evaluating the available bone, the condition of the neighbouring teeth, your bite, gum health and the exact position of the implant in relation to the anatomical structures. The implant procedure itself is performed under local anaesthesia, so the surgical placement should not be painful. Some swelling or discomfort for a few days is expected, but this is generally well controlled with routine medication. Regarding failure, no medical or dental procedure can carry a 100% guarantee. However, appropriate case selection, meticulous surgical technique, correct implant positioning, good prosthetic planning and regular maintenance significantly improve long-term predictability. One important advantage of seeing an Oral & Maxillofacial Surgeon is that the treatment can be planned from a surgical perspective as well as from the standpoint of the final tooth. If there is insufficient bone, for example, we can identify this beforehand and discuss bone preservation or augmentation rather than placing an implant in a compromised position. At 30, restoring the missing molar can also help maintain your chewing efficiency, occlusion and the surrounding bone and teeth over the long term. My advice would be not to make the decision based purely on anxiety about pain or failure. Have the implant site properly evaluated, understand the alternatives, risks, expected outcomes and costs, and then make an informed decision. A well-planned implant should be a carefully executed treatment—not something you need to be afraid.
