A. A bridge probably isn’t the best option- as you are compromising the health of 2 seperate teeth. An implant wit a fixed crown is often a good option, but firstly, you need to stabilise your gums before any treatment is done. If you have gum disease, then this is possibly the main cause of the tooth moving position anyway. Orthodontics is also a good option- but again, no treatment will be done until you can see an improvement with your gums. Ideally, you need to see a cosmetic dentist for a consultation to discuss these options in detail.
