Hi and thanks for your enquiry.

First of all I recommend you have your discoloured top tooth checked, to find out the cause of its discolouration, which could be an infection. Once the health of the tooth has been ascertained, then you can consider having a veneer or maybe a crown to improve the aesthetics of the tooth.

With regards to the gap at the bottom, you can consider:
-a denture
- a bridge (maryland being a type of bridge)
- an implant

It's very difficult to give approximate costs for bridges. Bridges are priced differently depending on the design of the bridge and the materials used.

This is just a general overview, but each case is different and I would stress the importance of an examination with a dentist to find out what is the best treatment for you.

Hope this helps

Kind Regards

Raha
