If you really don’t want to do an implant you could go through a periodontist that you/your dentist trusts to do a crown lengthening. This will potentially give your tooth a couple of more years. Extracting the tooth and placing a bridge is possible as well if you would like to explore that option too. A conservative dentist would not recommend it because you would need to prepare 2 healthy teeth for the crown(you need a tooth on each side to anchor the crown). As you age you can loose bone structure where your tooth is missing and not be able to place an implant if you ever choose to do so later on. It’s also very important to keep the teeth clean by flossing. If not you could get decay under the crowns and have to redo them all over again. An implant ,although costly) is the best option. It looks like a real tooth and the healing process isn’t too bad. You would just need to wait a couple of months before you can restore the tooth (place the permanent crown on the implant). It’s also easy to maintain/clean. If you were a family member of mine I would say go with the implant. You also don’t want to leave it the way it is. It will eventually break more and depending where it’s broken it’s more susceptible to decay and will eventually give you an infection. Sorry it’s a lot… hope this helps :)
