Black Triangles Between Teeth – Why They Happen & How to Fix Them

Black Triangles Between Teeth – Why They Happen & How to Fix Them

If you’ve started noticing small black triangles between your teeth near the gum line, you’re certainly not the first. Unlike some other dental issues, they can appear gradually as your gum changes or overnight after orthodontic treatment. Either way, your smile might start to look “off”.

While it tends to affect people over the age of 20, it can happen to anyone, meaning that a lot of people live with the problem every day. Naturally, when you’re dealing with something like this, you want a way to fix it.

In this blog, we examine what causes them and what your dentist in Manchester can do about the issue. Spoiler alert: There’s a lot that can be done.

What Causes Black Triangles Between Teeth?

So, what do we mean when we say ‘black triangles between teeth’? Rather than describing decay or staining, we’re talking about the gaps between your teeth and your gums that make that shape. The ‘black’ part is simply the darkness you can see behind your teeth.

Often, it’s a combination of the shape of your teeth, the way your gums sit, and changes that have built up over the years. That’s why they can appear even in people who keep up with their dental check-ups.

The starting point is understanding what’s actually happening.

It’s rarely just one of these on its own, as usually, it happens because a combination of things is converging. Even with the perfect dental routine at home, you can still be affected by these gaps.

Can You Fix Black Triangles Between Teeth?

Once those black triangles are there, they’re not going to close up on their own, but they can be fixed. As we’ve seen, it’s all to do with the gum tissue not filling the spaces between your teeth, so the treatment that sorts it out is going to be directly addressing those gaps.

The right treatment for black triangles between your teeth depends on what exactly caused them and how visible they are. The good news is that there are a number of options to choose from.

Composite Bonding

Composite bonding is one of the most popular ways to tackle black triangle gaps in teeth, and it involves bonding tooth-coloured material across the gap to improve the overall shape. It’s nice and straightforward and usually done in one appointment. Our guide explains more.

Porcelain Veneers

Porcelain veneers come into play when a more significant gap needs to be hidden, which is why they’re often used in smile makeovers. They sit over the front surface of the teeth and can be shaped to close gaps while also improving symmetry across the smile.

Orthodontic Treatment

When the position of the teeth is part of the problem, orthodontics can help by adjusting how they sit and meet. This can reduce or redistribute the gaps, and it’s particularly relevant when black triangles have developed after using Invisalign, hidden aligners or braces.

Gum Treatments

Where gum loss is the main driver of the problem, gum disease treatment can help improve how the tissue looks. They’re limited in what they can achieve though, and they’re not going to be the right fit in every case.

Can I Prevent Black Triangles Between My Teeth?

We’d love to be able to say they’re always controllable, but that would be wide of the mark. That said, there are quite a few things you can do to make them less likely to appear later. As you might expect, a lot of the tips below relate to how well you care for your teeth day to day.

Black triangles between teeth are common, but by doing the right things for your dental health, you can avoid them.

• Brush your teeth gently – Aggressive brushing can gradually push the gums back. It’s one of the most common causes.
• Keep your gums healthy – Bleeding or inflammation is worth getting looked at rather than ignoring it. The old phrase, “A stitch in time saves nine”, certainly applies in this case.
• Stay on top of hygienist visits – When plaque builds up around the gumline, it can contribute to the problem, so be sure to keep up with your dental hygienist appointments.
• Think carefully before getting aligners – While you might want straighter teeth, when yours are adjusted by orthodontic treatments, it can reveal gaps that weren’t there before.
• Deal with grinding or bite issues – Whether you’re a daytime or nighttime grinder, both can affect the teeth and the gum tissue around them over time. Our article on bruxism goes further.

Black triangles between teeth aren’t completely avoidable, but by doing these small things here and there, you can significantly reduce your chances of experiencing them in the future.

FAQs

Q – What are black triangles between teeth?

A – They’re the small dark gaps that appear between teeth at the gumline when the gum tissue no longer fills the space properly.

Q – Are black triangles permanent?

A – They won’t close up on their own, but they don’t have to be permanent. Once that space is there, it needs treatment to improve.

Q – Do black triangles mean gum disease?

A – Not necessarily. Gum disease can be a factor, but tooth shape, ageing, and orthodontic treatments can also make them happen.

Q – Can brushing too hard cause black triangles?

A – Yes. Too much prolonged pressure can wear the gums back. In fact, that’s one of the more common ways these gaps develop.

Q – Are black triangles more common after braces?

A – They can be. Moving teeth into a new position sometimes uncovers spaces that weren’t visible before, especially if the gums don’t fully adapt.
