I'm not sure if you mean to completely replace the teeth as in they are missing, or if you mean you have crowns currently and need those replaced. If you are missing the teeth completely, there are several options for replacement. Implants are fixed, do not come out, and will last many years. Expect to pay $4000-$7000 per tooth. Most insurances won't cover implants. You can have a bridge done. It is also fixed, but would involve shaving down the teeth on either side of the missing teeth. Expect to pay $1000-$3000 per missing tooth and per tooth holding on to the bridge on either side of the missing teeth. You can have a removable partial made. It would need to be removed at night to clean and let your tissue rest. Expect to pay $2000-$5000 total for a removable partial. Cost will depend on what material it is made of and how many teeth are missing.
Implants costs anywhere from $2,500 - $5,000 each depending on where you live and which dentist you go to? Then you’ll need the abutment and a crown to go on top of the implant and those are around $1,500 - $2,000 together. I’d say for the entire assembly (3 components) per tooth will cost on average $4,000 - 6,000 for each tooth so around $10,000 for both teeth. Implants take about 4-6 months to integrate with your jaw bone so some dentist will wait 6 months to place the crown on but some dentist will place the crown on immediately. Need to consult with dentists around you to see which route they prefer.
