Why do we need regular X-rays?
Your dentist will take regular X-rays to look for early signs of tooth decay.
Sometimes the tooth looks healthy, but your dentist will be able to see from an x-ray (radiograph) whether you have any decay between your teeth or under existing fillings, any possible infections in the roots, or any bone loss around the tooth. Finding and treating dental problems at an early stage can save both time and money.
In children, x-rays can be used to show where the second teeth are and when they will come through. This also applies to adults when the wisdom teeth start to come through.
There are various types of x-ray. Some show one or two teeth and their roots while others can take pictures of several teeth at once. The most common x-rays used at my dentist are small ones, which are taken regularly to keep a check on the condition of the teeth and gums. These show a few teeth at a time, but include the roots and surrounding areas.
