Kteercute, that’s a good question. Your not the only one to have this
concern.
Will those teeth need to be root canaled in the future due
to failed fillings? The answer is
not necessarily. Root canals are
needed because the tooth has “died”.
This occurs due to either decay extending into the nerve or history of excessive
trauma. So with fillings that are “leaking”,
if they are repaired or replaced before they get too big, then the likelihood
is, they will not require a root canal.
If there is a significant loss of tooth structure on the
back surface of the front teeth, like from GERD, and you are interested in
cosmetics for the front, then a full crown can be a better treatment choice. Isn’t not ideal to have two separate
materials on a tooth when one can cover/apply both surfaces/materials. If GERD is the concern, porcelain (from
a full crown) will last longer than a white filling. I hope that was helpful.
