Why take x-rays? 

So your dentist looks in your mouth, tells you everything is looking good and then recommends xrays.

What is the need?

Tooth decay can be clever. It gets underneath fillings, right down the side of the tooth underneath the gum or underneath the surface of the tooth and slowly progresses.

Unfortunately, these hard to reach places are almost impossible for us to see just by looking – xrays see ‘through’ the tooth, allowing us to spot it before it gives you toothache!
