People suffering from malocclusion could find that a visit to a dentist to talk about invisible braces is in order.

Writing for the Mirror, Miriam Stoppard explained that this is the medical term for a poor bite, when the teeth fail to meet at the back and slightly overlap at the front as perfect teeth do.

Instead, overcrowding or jaw shape could cause the teeth to become crooked, protrude significantly or overlap in an overbite.

"However, perfect teeth are rare and most people have some teeth that are out of position," Stoppard commented.

She pointed out that malocclusion often runs in families and said a specialist dentist may be able to help, particularly if it is causing problems with eating or speaking.

"If required, the teeth may be aligned using a brace," the expert commented.

Earlier this month, England rugby international Chris Ashton said in his Daily Mail column that he has been wearing invisible braces to correct his misaligned smile.
