I need six crowns on my front teeth. I was wonder if i should do them individually/separately or have all six connected together

If you have a strong bite, or you grind your teeth at night, or you have short roots, or you have recurrent gum problems, this is what can determine which type of reconstruction you might need, also the material, and if they would be individual or connected, making a bridge , it will be more stronger, but you will have more areas to clean in between.my recommendation would be for them to be individual. I hope this helps.

I would highly recommend them
being separate, unless you have periodontal disease and loss of bone around
these teeth and they are loose. If the crowns are splinted together, they
are much more difficult to clean and maintain and flossing can be a real problem.
The other factor is that if you have them all hooked together and you chip or
break one of the crowns, the entire 6 crowns will have to be replaced.
Keep them separate.

If your tooth are enough strong to put single crown the best and more comfortable to you is do it single.. but if you have a bridge now, or your teeth not are enough strong its better with a bridge.. the bridge give stability and do it more strong the teeth because are together.
