How To Remove Stains From Teeth At Home

To remove stains from teeth at home, first work out which kind of stain you have. Stains sitting on the enamel from food, drink, tobacco or vaping can be lifted, with a hygienist visit or whitening strips, and kept down with daily brushing. Staining inside the tooth responds to whitening but not to scrubbing. Tartar and decay are not stains you can shift yourself at all, and dental work keeps its own base colour whatever you do. This guide sorts yours into the right pile before you spend anything.

First, work out which kind of stain you have

This is where whitening goes wrong: a product bought for the wrong kind of stain does nothing, and whitening takes the blame. The American Dental Association splits tooth staining into two groups, and the split is worth knowing before you start.

Stain on the outside of the tooth

The ADA's definition is plain: "Extrinsic stains commonly result from an accumulation of colored compounds on enamel." Coloured compounds build up on the enamel from the things that pass over it. The ADA says this kind of discolouration is "primarily associated with environmental factors or individual behaviors", and names tobacco use and exposure to metal salts such as iron or copper, adding that it "can be exacerbated by lifestyle habits (e.g., smoking or chewing tobacco), poor oral hygiene".

The UK's Oral Health Foundation puts the everyday version of the same list in one sentence: teeth "can become stained by things like tea, coffee, red wine, and smoking."

This is the pile that responds to what you can do at home.

Stain inside the tooth

The second group is different. "Intrinsic stains occur inside the tooth (within the enamel or the underlying dentin)," says the ADA, and its causes have nothing to do with your coffee. It lists genetic conditions such as dentinogenesis imperfecta and amelogenesis imperfecta, local factors during tooth development such as fluorosis, certain antibiotics taken in childhood such as tetracycline, and "caries, amalgam restorations, and pulpal hemorrhage, decomposition or necrosis." Prolonged use of an antiseptic mouthrinse such as chlorhexidine can do it too.

Age belongs in this group as well, and it looks like staining without being any. "Aging is another common etiology of intrinsic discoloration," the ADA says: "With increasing age, enamel becomes more translucent and thinner, which allows the yellower dentin to show through". Nothing has accumulated on the tooth. You are seeing more of what was always underneath.

So the honest answer on this group is split rather than simple. The ADA's own summary is that "Whitening treatments can be effective on both extrinsic and intrinsic staining," because a whitening agent works chemically on the coloured compounds rather than rubbing at the surface. But the same page is clear that scrubbing will not reach them. Some over the counter whitening products, toothpastes and chewing gums among them, "are effective primarily in removing extrinsic (surface) stains on enamel" and "will not have a significant impact on intrinsic stains or the intrinsic color of the tooth". And it sets a ceiling even for whitening applied from outside the tooth, where "the removal of intrinsic stains within the dentin is considered near impossible".

Read together, that is a clear instruction. If the colour is coming from inside the tooth, no amount of brushing or polishing will touch it, a whitening agent may well help, and a dentist is the right person to tell you how much.

Brown stains on teeth, and when brown is not a stain at all

Brown marks are the ones worth slowing down over, because brown has more than one cause and only some of them are stain.

Brown from tea, coffee, red wine or tobacco is ordinary accumulated stain on the enamel, and it behaves like the first group above. If yours comes from smoking, we have looked at nicotine staining, and what whitening can and cannot do while you still smoke, in a separate guide.

Brown that has gone hard is not stain any more, it is tartar. Bupa's dental hygiene page, clinically reviewed by Caitlin Miller, Head of Dental Hygiene and Therapy at Bupa Dental Care, and last reviewed on 30 September 2025, puts it simply: "And if plaque builds up, it can harden into tartar, which can't be removed by brushing alone." Removing it is a physical job done with an instrument: "Your dental hygienist will scrape any plaque and tartar from your teeth using an instrument called a scaler." Nothing you buy in a box will do that.

Brown or black spots in one place, rather than a general shade across the tooth, need a dentist rather than a whitening product. The NHS lists "white, brown or black spots on your tooth" among the signs of a hole forming, and its advice is unambiguous: "See a dentist as soon as possible if you think you or your child has tooth decay." If the spots or marks appeared after braces, we cover what they can be, and who to ask, in our guide to stains and white spots after braces.

Nothing here is a substitute for being looked at. But a dark patch on one tooth, a rough or crumbling edge, or anything that has appeared alongside pain or sensitivity, is a reason to book an appointment rather than buy something.

What each home method actually does

Every method below does something specific, and the something is the reason it works on one pile of stain and not the other.

Brushing, flossing and a non-abrasive toothpaste

This is the floor, not the ceiling. The NHS describes the problem it solves: "Tooth decay happens when bacteria create a sticky layer called plaque over your teeth." Keeping that layer under control stops new stain settling and stops plaque hardening into something only a scaler will shift. On a tooth that is already stained it holds the line rather than turning the colour back, which is why the rest of this list exists.

A hygienist visit

This is the one to book first if your stain is accumulated and your last appointment was a while ago. Alongside scaling, Bupa says that if necessary the hygienist will polish the teeth with a special paste, which "helps to remove any stains from the surface of your teeth (the tooth enamel)". Bupa also describes AIR-FLOW therapy, where the hygienist sprays "pressurised air, water, and a fine powder between your teeth to remove any stains."

Abrasive powders, charcoal and baking soda

These work by scrubbing rather than by changing the colour of the stain, which is why they can lighten accumulated surface stain and do nothing at all to the colour of the tooth underneath. We have gone through what whitening powder actually does to a stain in detail, including what the evidence says about abrasion, so it is not repeated here. The other kitchen remedies, from oil pulling to strawberries and lemon, are taken one at a time in our guide to natural teeth whitening.

Whitening strips and gels

Strips are the category that reaches the stain chemically rather than mechanically, which is why they are the home option that can change the shade of a tooth rather than just clean it.

They come in two chemistries. Peroxide is the long established one, and in the UK the strength you can buy for yourself is capped by law, which is covered in full in our guide to the UK whitening rules. Peroxide works, and for some people it comes with sensitivity. If that is the reason you have avoided whitening, our peroxide-free whitening strips page sets out the alternative.

The second chemistry is PAP, which is short for phthalimidoperoxycaproic acid. It is peroxide free, and it still works on the coloured compounds inside the tooth, just by a gentler route than peroxide takes. If you want the chemistry rather than the summary, how PAP whitening works explains it properly.

PAP whitening strips are what Pure Glow makes, with hydroxyapatite and xylitol in the same formula, and the claim on the box is a ceiling rather than a promise: up to 6 shades whiter in 14 days, depending on where you start. The full list is on our Pure Glow facts and ingredients page.

Because the formula carries no peroxide, sensitivity is not the trade off, which is the whole reason the brand exists. There is a separate page on whitening strips for sensitive teeth if that is the thing that has put you off.

Two limits are worth being straight about. Strips will not re-colour a composite, a crown or a veneer: the Oral Health Foundation says plainly that "Whitening will not work on fillings, crowns or veneers, and it may not be suitable for everyone," and the ADA agrees that "Only natural teeth can be whitened, not tooth-colored restorations." What can lift is stain that has built up on top of dental work, which often helps it blend back in with the natural teeth around it. And strips will not remove tartar or treat decay.

When to see a dentist instead

Book an appointment rather than buying anything if any of these apply.

  • You have a brown, white or black spot in one place, or a rough or chipped edge.
  • Anything hurts, or has started being sensitive to cold.
  • Your gums bleed, are sore, or have receded.
  • It is the base colour of a filling, crown, veneer or bonded tooth that bothers you, rather than stain on top of it.
  • You have had hard deposits at the gum line for a while.
  • You have not had a check up for a long time. The NHS sets the trigger for an adult at two years since the last one.

It is also worth knowing who is allowed to do what. Asked whether you can have your teeth whitened at a beauty salon, the Oral Health Foundation answers no, and states that "Tooth whitening must only be carried out by a registered dental professional". Buying a cosmetic product and using it on your own teeth is a separate question, and it falls under the UK whitening rules mentioned in the strips section above.

The routine that stops the stain coming back

Lifting stain is the easy half. The sources above make the second half fairly obvious: the Oral Health Foundation's list of what stains teeth is tea, coffee, red wine and smoking, and Bupa's point is that plaque left alone hardens into something a brush cannot touch. So the routine follows from the causes rather than from any guidance of ours.

In practice that means keeping the brushing and flossing consistent so plaque never gets the chance to harden, having water with the coffee rather than after it, and getting the hygienist appointment in the diary rather than waiting until something looks wrong.

If you whiten, the same logic applies to topping up. A 14-day course gets you to a shade; keeping it there is two or three strips a week afterwards, which is what the 56 strip bundle saver is set up for. Our full routine for holding a result is in keeping teeth white after whitening.

And if the shade has not moved at all despite a clean mouth and a finished course, that is useful information rather than a failure. It points at the second pile, the colour coming from inside the tooth, and that is a conversation with a dentist.

Frequently asked questions

Can you remove tooth stains at home?
Accumulated stain on the enamel, yes. Whitening strips act on it chemically and daily brushing keeps new stain from settling. Tartar and decay cannot be dealt with at home, and dental work keeps its base colour, although stain sitting on top of it can lift.

What removes brown stains from teeth?
It depends what the brown is. Accumulated stain from tea, coffee, wine or tobacco responds to whitening and to a hygienist's polish. Hardened tartar needs a scaler. A brown spot in one place needs a dentist, because the NHS lists brown spots among the signs of a hole forming.

How do I get rid of yellow teeth?
Work out which of three things you are looking at: the natural colour of the tooth showing through, stain built up on the surface, or tartar. Each has a different answer, and we have taken all three apart in our guide to why teeth look yellow.

Does whitening toothpaste remove stains?
Some surface stain, yes, by abrasion. The ADA says some over the counter whitening products, including toothpastes and chewing gums, are effective primarily on extrinsic stain and will not have a significant impact on the intrinsic colour of the tooth.

How long does it take to lift stains with strips?
Our own course is one strip a day for 14 days, worn for a minimum of 30 minutes. When a change becomes visible varies from person to person, because it depends on how much stain is there and where your shade started. Checking your shade against a tooth shade chart before and after gives you a way to measure it rather than guess.

Will stains come back?
If the habits that caused them carry on, yes. That is what the routine section above is for, and it is why topping up exists.
