Perfect bite & alignment for 53 years but during last 2 years they're shifting. What best to do?

[David Jones]

Hi,

As my heading states I've had perfect bite and alignment all of my life but in the last 2 or 3 years my bottom 2 front teeth have started moving outwards and developed a 3 MM gap between each other when previously there was not gap.

I suspect that braces are the only answer?

But if so, won't the teeth start moving again once that procedure has ended?

Any advice very appreciated.

Thanks.

David
