Can the dentist replace the old bonding with a new one ? (Photo)

Of course you can redo the dental bonding again, and probably this is the least invasive dentistry treatment for you.
If you are thinking to just do your front tooth, you are way better off
bonding the one tooth, due to color matching on one tooth veneer will be
a challenge even for an expert veneer dentist.
Dental
veneer is much stronger than dental bond, however more tooth structure
removal is necessary than dental bond. Also they are more pricey. I
recommend you redo your dental bond, and if it fails then consider
porcelain veneer, but again not for one tooth.
Your
pictures also show asymmetrical gum lines, and you have a high lip line
( meaning you show your gum upon smiling). If you choose to do veneers
for strength and no staining later on, then I highly advise you to have
gum contouring also prior to having your porcelain veneers done,if you
do not, your veneers will look different length.

 Hello,Bonding and Veneers are both good options. You need to decide if you want a long term solution vs. a shorter one. Consider the following:Veneers:Natural lookingLast longer Color stableConsistant color with no visible marginRequired more preparation of enamel then bondingMore expensiveUsually sent to a lab and requires 2 visit about 1-2 weeks apart. Bonding:Tend to look flat if not layered correctly Shorter life spanDiscolor overtime Margins become visible overtimeRequired less preparationLess expensive.Usually done in one visit chair-side for immediate solutionMy recommendation is to determine what you want to achieve and consider the costs. Veneer cost can range from $1500-$2500 depending on the area you live in, whereas Bonding tends to be much less and range from $500-$1000.  Although Veneer tend to be more expensive and require more tooth preparation, they may be the best recommendation for your front tooth.  Best regards,

u have two options. either u can go for direct bonding or porcelain veneer. but its my personal advice to go for porcelain veneer. it will give u more natural look and main advantage is ,no chances of staining.

Hello,You do have a couple of options. One is to replace the old bonding with a new one. The composite or white filling material is used to replace the cracked part. The material gets bonded to the tooth. To make this bonding stronger, the dentist would have to roughen up an area of the tooth that he wants to place the bonding. The bonding might get dull after a while and would need to be polished or replaced. Your other option is a porcelain veneer. To place a veneer, the dentist would need to remove more of your healthy tooth structure and the veneers for the front teeth would look much nicer done for both of your front teeth at the same time and that would also require more removal of enamel. Porcelain veneers stay shiny and don't get dull with time. Remember , there is always the possibility of getting cavities under any restoration ( bonding or veneer). In conclusion, I would recommend replacing the bonding first since it is a more conservative option and see how you like the results.  Hope this helps !

Bonding can be re-done to match the color of your natural tooth. If you'd like your teeth whiter, it would be a good idea to bleach before re-doing the bonding so that the color matches better. It is difficult to gauge the size of the filling by the picture, but sometimes when the bonding is very large, it may be better to veneer or crown the tooth for better long-term stability. It doesn't hurt to try to do bonding first, and if you're unhappy with the results, discuss your options with a dentist.
