You can restore your teeth to their natural shape and colour!
A dental crown is a tooth-shaped "cap" that is placed over a tooth to improve its strength, shape, size, and improve its appearance. The crowns are custom made by the laboratory. When cemented into place, fully encase the entire visible portion of a tooth that lies at and above the gum line.
They are great solution for a heavily broken, discoloured and missing teeth.
