Let's face it - all any of us really want is a sparkly white set of gnashers to have the perfect Hollywood smile.
Now, we all have differences when it comes to our teeth, but some of you may be wondering what it means if you have black triangles between your teeth.
Well, wonder no more as one dentist has come to the rescue to explain what causes them and what you need to do to take care of them properly.

Dr Abdul Azizi, Principal Dentist of Harley Private Dental Clinic, has explained that 'black triangles' between your teeth are basically just the empty spaces or gaps that can develop between teeth.
The gaps, which often appear near the gum line, tend to have a darker appearance as they expose the underlying oral tissues and may trap rogue bits of food, plaque build-up, or other debris which makes them more noticeable.
Dr Abdul says: "Black triangles between your teeth are not inherently dangerous but may be associated with oral health concerns, like gum disease or gum recession.
"They are not necessarily a sign of poor hygiene, as various factors, including genetics and tooth shape, can contribute to their development.
"However, they can trap food particles and impact oral hygiene and aesthetics, which may warrant dental attention for cosmetic or preventive reasons."
The dentist explains that there are 'several potential reasons' why black triangles may start forming in between your pearly whites.
First up is gum recession - which occurs when the gum tissue that normally covers the roots of teeth begins to pull away, exposing part of the tooth's root.
Next up is bone loss and periodontal (gum) disease which can lead to the loss of bone support around the teeth, which can result in the gums pulling away from the teeth, leaving open spaces.
Variations in tooth size, shape, and alignment can also create gaps or black triangles, particularly if the teeth are not perfectly adjacent to one another.
Fourth is down to the natural process of simply ageing.
As we age, Dr Abdul informs, changes in gum tissue and bone density can contribute to black triangles.
And last up is orthodontic treatment like braces or aligners which can sometimes alter the position of teeth and create small spaces or black triangles.
So, the question we're all wondering - can these pesky black triangles ever be prevented?
While it can be challenging, the dentist assures that there are a bunch of measures people can take to help minimise the risk.
Keeping up good oral hygiene, having regular dental check-ups, gently flossing, avoiding smoking, correcting misaligned teeth through orthodontic treatment and generally managing underlying health conditions can all help.
But what if you've already got black triangles?
If you're bothered by them, Dr Abdul suggests discussing potential treatment options with a dentist or orthodontist.
Such options may include, dental bonding, dental veneers, gum grafting or undergoing orthodontic treatment to move teeth and close the gaps.
"The best approach to address black triangles between your teeth will depend on the underlying cause and your specific oral health and cosmetic concerns," the dentist adds.
"It's important to consult with a dentist or orthodontist to determine the most appropriate."
