Thank you for your inquiry. If you're interested in getting just a whitening and then bonding to help with your teeth color and small anterior gap, the cost will depend on what office you go to since each office pricing varies depending on where you live. For example, pricing in a place like Texas may differ from pricing in a bigger city such as Los Angeles or New York City. If you have dental insurance, speak with your dentist about possibly being able to get some of your bonding covered under your plan. Some insurance plans may cover part of your procedure although whitening is typically not a covered benefit. You may be able to have some nice results from just whitening and then bonding. For whitening, you can try at home kits, get custom trays from your dentist, or even complete a one hour in office Zoom whitening. If your teeth are "naturally yellowish in color" then don't be surprised if your teeth don't whiten a significant amount. Your bonding can be completed to match your teeth shade after your whitening is completed. Getting a good teeth cleaning before you try whitening may also help with your results. We hope this helps and best of luck to you!
