I broke my 25% front tooth? should i go for tooth colored resin filling because i don't want any of my remaining natural tooth structure removal?

Yes: As long as there are no other areas of decay on the tooth or nerve exposure. A composite filling may be a good option. Be aware that in cases of tooth trauma the nerve may have been damaged as well. Your dentist will work with you on monitoring your tooth as well as the adjacent teeth. Look for signs of pain under your nose or a darkening of your tooth, either of these situations is not favorable.

Hard to say: Tooth colored restorations are not strong enough to rebuild a major part of your tooth if the restoration is unsupported and you have a deep bite. It is possible to do this in certain fractures, but long term it may not last. Your restorative dentist can give you the options for your specific tooth. All the best..

Broken tooth: Depending on how much and where the break is located, as well as what forces you place on the tooth will help determine design. A bonding is more conservative but can be difficult to match esthetically and is weaker than ceramic. You can always try the bonding and if it does not last move up to a conservative veneer. Conservative bonding is a great option. See a trained cosmetic dentist.
