Why Do My Teeth Look Grey? Causes & Solutions

Why Do My Teeth Look Grey? Causes & Solutions

Often, when people start thinking about teeth whitening in Manchester, it’s because they’ve been noticing their smile lacking something for a while. Teeth don’t just turn from white to grey overnight, but when it’s impacting your confidence, you don’t want to leave it any longer than necessary.

2 out of every 3 adults in the UK have actively considered teeth whitening, as more people than ever are concerned about how their smile looks. In fact, according to the British Dental Foundation, it’s causing more dentist visits overall.

So, if you’re familiar with that feeling of not wanting to open your mouth during photos, this article is for you, as we look at not just what’s behind teeth greying, but also what you can do about it.

What Causes Grey Teeth?

Unlike a surface stain that you can put down to drinking coffee or red wine, tooth greying is something that creeps in day by day. These changes usually go completely under the radar until it becomes visible. That’s when teeth whitening in Manchester comes into the conversation.

While greying of the teeth can come from external influences, it tends to come from within, with something else happening underneath. Here are just some of the factors that could be behind it:

• Natural ageing and enamel thinning – Your tooth enamel wears down slowly as you age, becoming more translucent as it does. Then, the darker dentine sitting underneath starts to show through, and that can give teeth that flat, slightly grey appearance.
• The wear and tear of life – Grinding puts a lot of pressure on enamel over time, but even normal day-to-day life can take its toll. Again, as time passes, the enamel thins and looks duller.
• Everyday staining – The more your tooth enamel thins, the more your day-to-day routine can take away your smile’s lustre. Coffee, tea, wine, soy sauce, and even balsamic vinegar can cause greyness.
• Old fillings or dental work – While composite fillings are preferred these days, older metal fillings can give your teeth a much darker hue, particularly through thinning enamel.
• Root canal treatment – If the tooth in question has had root canal treatment, there’s no longer anything living inside it. Given enough time, that shows, with the tooth ending up noticeably darker.
• Trauma or injury to a tooth – If you’ve had a blow to the face, it can cut off the blood supply inside. This usually affects just one tooth, making it much easier to spot than general greying.

In the main, teeth usually become grey very slowly, over the years. As such, think about whether it’s one tooth or many, because it will tell you whether or not it’s a cosmetic dentistry issue. 

Do you have a problem with yellowing, rather than greying? Our article talks you through why they turn this colour and what you can do to change it.

Can Teeth Whitening Restore a Grey Tooth?

It can help in some cases, but not all. For example, if your teeth have gone greyer over the years, teeth whitening in Manchester can help to lift the overall shade and make your smile look brighter.

However, greyness can be more stubborn than yellowing, meaning results aren’t as easy to achieve. Also, it depends on the reason for the greying, as there are times when whitening won’t do much at all.

Here’s an overview:

The main thing here is to keep your expectations realistic. Sure, whitening can make a noticeable difference. However, treatments like a scale and polish and whitening don’t do a lot because the issue lies beneath the surface.

What Are the Alternatives to Teeth Whitening in Manchester?

The good news is that there are other options that can deal with tooth greying, even when the root cause is inside. Rather than trying to lift the shade from the outside, the treatments here target the discolouration directly at source.

Let’s take a look at some of the treatments your dentist in Manchester might recommend when tackling a greying tooth.

Internal Whitening

If the tooth has had a root canal or is no longer “alive,” whitening can sometimes be done from the inside. It involves your dentist putting a bleaching agent into the tooth and sealing it while it works with a temporary filling.

Composite Bonding

If it’s just one grey tooth, this is often where dentists start. Rather than trying to change the colour of the tooth itself, they cover it. A tooth-coloured material is shaped over the front so it blends in with everything around it.

Composite bonding is quick, usually done in a single visit, and doesn’t involve much drilling. For a lot of people, that’s enough to make the problem more or less disappear.

Veneers

Veneers are another way of dealing with a grey tooth, which works by covering the colour rather than trying to change it. A thin layer is placed over the front so the darker shade underneath doesn’t show through.

They can be done in two ways:

• Composite veneers are built directly onto the tooth in one visit, using a tooth-coloured material shaped by the dentist.
• Porcelain veneers are made separately and then fitted, giving a more uniform finish. It’s more of a commitment than bonding, so it’s usually only considered if the tooth is particularly noticeable.

Essentially, if the greying is coming from inside the tooth, no amount of teeth whitening is going to change it. When that happens, the only way to lighten it is to cover it or lighten it from the inside.

FAQs

Q – Are grey teeth something to worry about?

A – Usually not. If the colour has changed gradually across several teeth, it’s just part of ageing and enamel wear. If one tooth changes colour on its own, it’s worth getting it checked, not because it’s urgent, but to rule out anything going on inside.

Q – Why do grey teeth often look worse in photos?

A – Grey tones don’t reflect light as well as brighter shades, so they can look more noticeable under flash or artificial lighting. That’s often when people first realise something’s changed.

Q – Can a hygienist clean make grey teeth look better?

A – A hygienist appointment can help a bit. If there’s surface staining on top of the grey tone, a clean can lift that and make your teeth look fresher. It won’t change the underlying colour, but it can stop things looking dull.
