Crowns are a type of dental restoration which when cemented into place, fully cap over the portion of a tooth that lies at and above the gum line. (Whereas fillings are dental restorations that fill in or cover over just a part of a tooth).
When Do You Need Crowns?
A dentist would usually recommend placing a dental crown for one of the following reasons:
• To restore a tooth to its original shape
• To strengthen a tooth
• To improve the cosmetic appearance of a tooth
At Ashton and Lonsdale Dental Practices, we have experienced dental practitioners who can advise on the best type of material to be used for your crown.

Which Material Is Best?
Crowns are made out of porcelain (dental ceramic), metal (gold or other metal alloys) or a combination of both.
Gold – It is strong and flexible, it expands and contracts at the same rate as natural teeth so prevents your gold crown from chipping, cracking or breaking; It will not darken or stain over time; It is relatively smooth and is very easily cleaned.
Porcelain – It can be matched to the exact shade of the rest of your teeth so are the most cosmetically pleasing; Although very life like in appearance the overall strength is less than other types of crown; Porcelain is microscopically rough so food and bacteria may easily stick to it.
Porcelain Fused To Metal – These types of crowns are strong enough to withstand heavy biting pressures and can have an excellent cosmetic appearance.
