WHEN you meet someone for the first time, you can often be struck by their smile.

While your new friend might have a gleamy set of pearly whites, the state of their teeth might reveal more than just their brushing routine.

Cosmetic dentist Dr Sahil Patel said your teeth could actually give away various personality traits.

Dr Patel, who is the founder of Marylebone Smile Clinic, said there are four key types to look out for.

Squoval

While you might be more used to asking a nail technician for a squoval shape, Dr Patel said this is also a common tooth shape.

Squoval has rounded corners with an element of squareness and Dr Patel said it suits most personalities and is considered a safe shape for teeth as it does not impute any strong personality effects.

"Considering most people’s facial profiles, on average we show sharp angles at the angle of our lower jaw, upper cheek bones and forehead.

"These angles are softened by the nature, shape and level of fat within the skin overlying the bone structure. 

"Squoval teeth could suggest traits such as sophistication, calmness and affability", he said.

Oval

If you have oval teeth then they will be rounded which is more feminine and a youthful shape, Dr Patel said.

When it comes to who these teeth would suit, he said aesthetically, rounded facial features would suit rounded or ovoid teeth.

"Oval teeth impute a carefree, positive and outgoing personality", he added. 

Square

Square teeth are on the opposite end of the spectrum compared to oval teeth, and they tend to be flatter in the edge profiles with sharp corners, Dr Patel said.

He explained: "They are a masculine and older tooth shape and over time almost everyone will wear their teeth into a more square looking appearance.

"Square teeth is not necessarily a bad thing for everyone, but they are associated with older age due to the effects of tooth wear.

"Age-appropriate teeth are becoming a little more popular in recent times due to people wanting a natural aesthetic. 

"Personality traits could include seriousness, maturity and efficiency."

What does tooth shape mean for you?

Dr Patel says that if you are wanting to change your smile then a good starting point is to look in the mirror and see what type of facial form and corresponding tooth form you currently have.

He explained that this is what nature has given you and that for most cases it's not far off the best smile you can get.

"That being said, if you have something you are looking to change or improve, consider where you might fit in with the personality traits, and remember that cosmetic dentists can mix tooth forms together.

"For example, a squoval tooth form can be made to be more on the ovoid side or more square, whilst still retaining some features of squoval", he added.

Triangular

If you have teeth that flare outwards a lot then Dr Patel said this could be a defining trait. 

"Triangular teeth are associated with dominance, creativity, motion, free thinking and quirkiness", he said.

Dr Patel explained that individual teeth might also take their own shape and added that some people might also have pointy canines.

This, he said, is usually associated with masculinity, strength and aggression.

Other things to look out for, he said, are white spots on the teeth, which can give teeth character and show openness, kindness and creativity.

He added that many people will also have uneven edges on their teeth as a result of natural wear and tear.

"Asymmetric features such as chipped or cracked teeth could show disorganisation, reduced intelligence, but also creativity and extroversion", he added.
