Healthy gums feel firm, hug each tooth and range from pale coral pink to dark brown, depending on how much melanin your body makes. A change in color is what should catch your eye. Red, purple, white patches, a pale tone or a new dark spot each point to a different cause, from gingivitis to anemia.
If you're checking your gums in the mirror and wondering what's normal, this guide shows you what each color means and when to book a dentist. Gum disease is common: CDC data show 42% of US adults aged 30 and over have periodontitis. At our family dental care in Vista practice, we check your gums at every visit.
Normal gum color: what healthy gums look like
Healthy gums look pink, coral or an even brown. They feel soft but firm, sit snugly around your teeth, and don't swell, feel tender or bleed when you brush or floss. The tone stays the same from tooth to tooth.
Your gums don't have to be pink. Mayo Clinic notes that healthy gum color runs from light pink in some people to dark pink and brown in others, depending on genetics and skin pigmentation.
Gum color chart
An even pink to brown is normal. Red, purple, white, pale or yellow gums each have their own likely cause and next step, and so does a new dark spot.
- Pale coral pink to even brown
- Likely cause: This is normal. Your shade depends on how much melanin your body makes.
- When to see a dentist: At your routine checkup.
- Bright red or dark red
- Likely cause: Gingivitis, usually from plaque at the gum line.
- When to see a dentist: Book a cleaning and exam soon. Gingivitis reverses with care.
- Dark purple or bluish
- Likely cause: Periodontitis. Bluish gums and lips together mean low blood oxygen.
- When to see a dentist: As soon as possible. Call 911 if you also have trouble breathing.
- Pale or white
- Likely cause: If the whole gum is pale, anemia. If there’s a white patch, leukoplakia or thrush. Whitening gel can also irritate gums and turn them white.
- When to see a dentist: Get an exam for any white patch that hasn’t healed in 2 weeks. If your gums are pale and you also feel tired, see your physician.
- Yellow
- Likely cause: Plaque and tartar at the gum line. If your eyes and skin are yellow too, jaundice.
- When to see a dentist: Book a cleaning for plaque. For jaundice, call your physician the same day.
- Black, gray or dark spots
- Likely cause: Melanin pigmentation, smoking, or an amalgam tattoo near an old silver filling. Rarely, melanoma.
- When to see a dentist: Any spot that is new, growing or irregular needs an exam, and possibly a biopsy.
What different gum colors can indicate
Each color change has a short list of common causes. The same color can mean different things depending on whether it covers all your gums or sits in one spot.
Red gums
Bright red or dark red gums signal gingivitis, the earliest stage of gum disease. Mayo Clinic lists "bright red or dark red gums, or gums that are darker than usual" among its symptoms. Plaque building up at the gum line is the main cause, and brushing and flossing on and off lets it build. Hormonal changes from pregnancy, the menstrual cycle or birth control pills can also redden gums.
With red gums, you'll often notice swelling or puffiness, bleeding when you brush or floss, and some tenderness.
Dark red, purple or bluish gums
Dark red or purple gums point to periodontitis, the stage of gum disease that damages the bone around your teeth. Mayo Clinic lists bright red, dark red or dark purple gums among its signs.
Bluish gums have a different cause. MedlinePlus explains that a bluish color in the gums, lips and nail beds usually means too little oxygen in the blood, a condition called cyanosis. If you have bluish skin along with trouble breathing or chest pain, call 911.
Pale or white gums
If your gums look pale all over, think anemia, which the National Heart, Lung, and Blood Institute lists as a cause of paleness. A white patch in one area has other causes.
White or gray patches that you can't wipe away are leukoplakia, which Mayo Clinic links to tobacco use above all. Creamy white patches that bleed a little when scraped point to oral thrush, a yeast infection. Peroxide gel can also turn your gums white for a day or two, and our guide to whitening near your gums explains why.
Yellowish gums
Yellow along the gum line comes, in most cases, from plaque and tartar on your teeth. A yellow tint across the gums, together with yellow skin and eyes, means jaundice. Cleveland Clinic describes jaundice as yellowing of the skin, the whites of the eyes and mucous membranes such as the inside of the mouth, and says a healthcare provider should evaluate it.
Orange gums
No gum disease turns gums orange. If you see orange, you're looking at one of two things in nearly every case.
The first is stain on your teeth right at the gum line. A 2019 review by Fiona Collins for the Colgate Oral Health Network links yellow, orange, green and black stains to pigment-producing bacteria, mostly in children, and notes that a routine professional cleaning removes them.
The second is red, inflamed gums that look orange-red under warm bathroom light. If the orange area bleeds when you brush, treat it as red gums.
Black or dark spots
Dark gums are, in most cases, normal pigmentation, and you'll see it more in people with darker skin. A sudden change or an irregular spot needs a dentist's exam to rule out other conditions, including melanoma.
Are dark gums normal?
Yes, if the color is even, matches on both sides and has always been there. The brown comes from melanin, the same pigment that colors your skin. A single spot that is new, growing or uneven is a different story and needs an exam.
A 2024 study of 839 adults in BMC Oral Health by Koppolu and colleagues found that people with darker skin had more melanin pigmentation in their gums, and that published rates of gum melanin pigmentation range from 0 to 89% between populations. In the authors' words, "these variations are normal."
Three other things can darken your gums.
Smoking and secondhand smoke
Tobacco smoke stimulates melanin in the gums, a pattern called smoker's melanosis. A 2017 study of 200 non-smokers in the European Journal of Dentistry found a correlation between secondhand smoke exposure and gum pigmentation.
Amalgam tattoo
A flat gray, blue or black spot next to an old silver filling is, in most cases, silver particles in the gum. Hygienist guidance published in 2024 notes that an amalgam tattoo doesn't change size or color once it has formed.
Addison's disease
The National Institute of Diabetes and Digestive and Kidney Diseases lists darkening of the lips and the lining of the cheek as a sign of adrenal insufficiency. If you notice new darkening that spreads, along with fatigue and weight loss, ask your physician.
When gum color is a warning sign
Pay attention if the color changes, if a patch hasn’t healed in two weeks, or if the change comes with bleeding, swelling or symptoms elsewhere in your body.
- A white or red patch that hasn’t healed in 2 weeks
- Why it matters: Mayo Clinic says leukoplakia with red areas (speckled leukoplakia) is more likely to show precancerous changes.
- What to do: Book a dental exam and oral cancer screening.
- A new, growing or irregular dark spot
- Why it matters: Oral melanoma is rare, but it can look like harmless pigment.
- What to do: Get an exam, and a biopsy if the spot has changed.
- Red or purple gums that bleed
- Why it matters: This points to gum disease. The CDC says severe periodontitis affects about 8% of adults.
- What to do: Book an exam and cleaning within the next few weeks.
- Blue gums and lips with shortness of breath
- Why it matters: Your blood oxygen is low.
- What to do: Call 911.
- Yellow gums with yellow eyes or skin
- Why it matters: This is a sign of jaundice.
- What to do: Call your physician today.
- Pale gums with tiredness or shortness of breath
- Why it matters: You may have anemia.
- What to do: See your physician and get a blood test.
Mayo Clinic advises seeing a provider for white patches or sores that don’t heal on their own within two weeks, and for any white, red or dark patch that doesn’t go away.
In a 2023 CMAJ case report, Ryo Sasaki, Sekiko Taneda and Toshihiro Okamoto wrote about dark spots: “Melanoma should be ruled out for any pigmented gingival lesion.” Most spots turn out to be pigment or an amalgam tattoo, and an exam tells you which.
Other warning signs in your gums
Color is one clue. Bleeding, recession and bad breath tell you as much, so look out for:
- Bleeding or tenderness that keeps coming back
- Gums pulling back from your teeth
- Pockets forming between your teeth and gums
- Bad breath that brushing doesn't fix
- Pain or discomfort when you chew
If you catch gum disease early, you can stop it before it loosens teeth. The CDC counts 42% of US adults aged 30 and older with periodontitis.
Causes of gum color changes
Gum color changes come from oral disease, habits, medications and conditions elsewhere in your body. The common causes:
- Gum disease (gingivitis and periodontitis)
- Low vitamin C, which Mayo Clinic lists as a gingivitis risk factor, and iron deficiency anemia
- Hormonal changes from pregnancy, the menstrual cycle or birth control pills
- Smoking or tobacco use, a risk factor for both gum disease and darker pigmentation
- Medications, including phenytoin and some calcium channel blockers, which Mayo Clinic lists as gingivitis risk factors
- Conditions such as diabetes (which the CDC associates with serious gum disease), anemia and liver disease
At regular checkups, your dentist can spot the cause early and treat it.
How dentists diagnose gum problems
At each checkup, your dentist looks at the color, texture and shape of your gums, checks for bleeding or inflammation and looks for plaque and tartar. They also measure the depth of the pockets between your teeth and gums.
If a spot or patch looks suspicious, a biopsy shows what it is. If the color points to anemia, jaundice or another condition elsewhere in your body, your dentist will suggest blood tests through your physician.
Treatment and care for healthy gums
Treatment depends on the cause. Your dentist treats gum disease with cleaning and sometimes medication, and color from melanin needs no treatment.
Professional treatment
- Deep cleaning, called scaling and root planing, for gum disease
- Medication or antibiotics for infections
- Surgery for severe periodontal disease
You can reverse gingivitis. Mayo Clinic notes that early care improves your chances of reversing the damage before it becomes periodontitis. Our guide to reversing gum disease explains the steps.
At-home care
- Brush twice a day with fluoride toothpaste and a soft-bristled brush
- Floss once a day to clear plaque between teeth
- Use an antiseptic mouthwash if your dentist recommends one
- Eat a balanced diet with enough vitamin C and calcium
- Stay away from smoking and chewing tobacco
Preventing gum problems
Prevention comes down to clearing plaque every day and having a hygienist remove what you can't reach. Book a professional cleaning every six months, or more often if your dentist recommends it. Cut back on sugar and acidic foods, and drink enough water through the day.
Myths about gum color
Three myths cause most of the worry about gum color.
People expect gums to be bright pink. Healthy gum color varies with genetics and skin tone, from light pink to brown.
Some people think bleeding gums are normal. Bleeding points to irritation or early gum disease, and your dentist should check it soon.
It's easy to assume gum disease stays in your mouth. The CDC associates diabetes with serious gum disease, and doctors manage the two together.
Checking your gums at home
Compare your gums with how they normally look. Even pink or even brown that has always been there is healthy. Red or purple gums that bleed point to gum disease. A pale or yellow tone needs a physician's check, and a white patch or new dark spot that lasts past two weeks needs a dental exam. A mirror check will show you the change, and your dentist can tell you what caused it.
Frequently asked questions
Can gum color change overnight?
In most cases gum color changes over weeks. A sudden change points to irritation, injury or infection: white tissue for a day or two after peroxide whitening gel, redness from a new toothpaste, or swelling from an abscess. Mayo Clinic advises an exam for any white or red patch that hasn't healed within two weeks.
How can I improve pale gums?
Treat the cause, which is most often anemia. The National Heart, Lung, and Blood Institute lists paleness among anemia symptoms, so start with a blood test through your physician. Iron-rich food helps only if you're low on iron. In the meantime, good brushing and flossing keep the gum tissue healthy.
Are red or inflamed gums reversible?
Yes. You can reverse gingivitis, the early stage of gum disease, with better brushing, daily flossing and a professional cleaning, and Mayo Clinic notes that early care prevents periodontitis. Left alone, it progresses: the CDC estimates 42% of US adults aged 30 and over already have periodontitis, which needs deeper treatment.
How often should I have my gums checked?
At every routine dental visit, which for most people means every six months. If you have gum disease or diabetes, or you've smoked, you may need visits more often, because the CDC links poor oral hygiene, diabetes and smoking with serious gum disease. At Main Street Dental, we check your gums at every exam and cleaning.
Why are my gums orange?
In most cases the gums themselves are fine. The orange tends to be bacterial stain on your teeth at the gum line, which a 2019 Colgate Oral Health Network review links to pigment-producing bacteria and which a professional cleaning removes. Red, inflamed gums can also look orange-red in warm light. If yours bleed, treat them as gingivitis.
