Gums bleeding for no reason / night / brush / floss - Dental Health Pick (2022)

Why my gums bleeding for no reason without brushing, and sometimes at night?

Gums bleeding for no reason is not a good sign. Healthy gums would never bleed unless you physically puncture them with a sharp object. Just like a skin on your arms, legs, or anywhere else on your body should not bleed unless it’s cut.

Here are a few reasons why your gums may bleed for no reason during the day, at night, when you create suction in your mouth, or when brushing and flossing your teeth;

1. Gum disease.

The most common reason for bleeding gums is the gum disease. You may have an early stage of gum disease – gingivitis, or an advanced stage of jaw-bone disease – periodontitis. In either case, your gums may bleed when you floss or brush your teeth. They can even bleed for no reason at night while you are asleep.

The gum disease mostly develops when you forget to clean your teeth on regular basis. Oral bacteria multiply very fast creating a thin layer of slimy plaque. If you don’t thoroughly brush your teeth to remove that goopy plaque, it hardens into rough stone-like tartar (calculus).

Calculus will irritate your gums and make them bleed. Furthermore, the rough surface of calculus will invite even more bacteria and exacerbate the infection and further calculus buildup.

Visit your local dental office as soon as possible. If caught early, the calculus buildup can be removed in one session by a dental hygienist. The procedure is quick, inexpensive and almost pain-free.

If you wait too long, a simple gum disease – gingivitis will progress into jaw-bone disease – periodontitis. The late stage of gum disease costs about 10 times as much to treat, it’s more painful, and you still may lose some of your teeth because of it.

2. Puberty.

Congratulations, you hit puberty! Whether you are a boy or a girl, teenage years bring a lot of changes to your body. Some parts will become more sensitive and that includes your gums and teeth. You may get a mild form of gingivitis, mouth sores, and bleeding gums for no reason during the day or at night.

There is no medical treatment for that… you just have to go through these changes until you become an adult. However, you must practice a good oral hygiene at home on a regular basis.

Continue to brush your teeth twice a day, floss, and use alcohol-free mouthwash to reduce the chances of getting a jaw-bone disease – periodontitis. Also, consider getting a water-flosser to clean and massage your gums, to make them stronger.

3. Pre-Menstrual gingivitis.

You may have noticed that your gums bleed on a monthly basis a few days before the menstrual period starts. This is not common but may happen. Your gums will become swollen, tender, and can bleed for no reason.

Menstrual gingivitis happens mostly due to an increase in progesterone production, but it’s temporary. Typically it will go away as your regular cycle starts. However, if you have preexisting gum disease it may be exaggerated by your menses.

To reduce the pain and discomfort of pre-menstrual gingivitis and bleeding try some of the home remedies;

  • Clove Oil, Coconut Oil, and Aloe Vera Gel can be applied directly to the sensitive gums a few times a day for about 10 minutes. Then swish your mouth with plain warm water and spit it out.
  • Tea Tree Oil works wonders as well, but it’s too strong for your gums. Mix few drops of Tea Tree Oil with something like a spoonful of Almond Oil and swish the mixture in your mouth for 10 minutes and spit it out. (Do not swallow it)

4. Dental bridges and crowns/caps

Your gums may bleed for no reason only in one area under an old bridge or a crown (aka cap). Dental bridges are probably the most troublesome. While you could easily floss on both sides of a single crown, it’s not possible with a bridge.

A dental bridge needs to be flossed on all four sides (two outer-sides and two inner-sides). To get to the inner-side you need a Dental Floss Threader or a Soft Toothpick. If you ignore this important step, your gums may still bleed at the bridge, even if you floss and brush everywhere else.

Bad dental work

Gums bleeding under bridges and crowns may not be your fault.

Whether you have a crown, a bridge, or a tooth filling they should not make your gums bleed for no reason. However, some dentists create poor dental work. Crowns and fillings may cause irritation and inflammation of your gums. Even if you keep your mouth clean on regular basis, inflamed gums may still bleed.

Any dental work in your mouth should be polished smooth and feel like your natural teeth. If you feel rough spots on your teeth with a tongue, that area will attract bacteria and cause your gums to bleed.

Note: rough spots on your natural teeth, also, maybe a tartar buildup which can easily be removed by a dental hygienist.

Crown “overhang”

Dental crown overhang doesn’t happen often now-days, but it can cause bleeding gums and other serious issues. A crown-overhang is when the crown is larger than the tooth it is sitting on. (Think of it as a mushroom or an oversized roof sticking out from a tiny house)

Every time you have a meal, some of the food particles will “hide” under that overhang. That is a perfect spot for bacteria to breed and multiply right under your gums. Your body’s’ defense system will try to fight the bacteria, and in the prosses will create a bloody pus.

When there is no room to expand, that bloody substance will come out from under your gums. This can happen anytime during the day or at night for no reason, or when you create a suction pressure in your mouth.

Unfortunately, it’s impossible to tell the difference between the good dental crown and the bad one just by looking at it. Therefore, if you suspect that the crown makes your gums bleed, it is in your best interest to visit a dentist. A dental professional will be able to check for overhang and recommend a solution for your problem.

Dentures

If you are at the point of life where you have to wear dentures this may get really uncomfortable. Your dentist will try to make dentures to fit right the first time, but most likely it’s not going to work. Don’t hesitate to come back for readjustments as it’s necessary.

Ill-fitting dentures will sit uncomfortably and make your gums bleed. Even if your dentures fit well right now, next year you may feel differently. When you lose all of your teeth the jaw bone will shrink about 1mm a year. So, dentures that fit you today may not fit you next year.

Every time you chew and bite on something it increases the shrinkage of the bone. To reduce the bone loss prosses, remove dentures from your mouth as often as possible. Especially at night, if you grind or clench your teeth take dentures out to slow down the bone resorption.

To eliminate the prosses of bone loss, you will need to replace your lost teeth with dental implants. The procedure can get really expensive, but you will save the jaw bone from shrinkage, and gums from bleeding.

5. Mouth breathing

We all know that breathing through the nose is better than mouth-breathing. But how does it affect your gums, and why they bleed for no reason?

If you have Chronic Nasal Obstruction, your body doesn’t get enough oxygen by breathing through the nose. Therefore, you start breathing through your mouth involuntarily. Especially at night, when you have no control over your actions, you could breathe through your mouth for 8 hours straight.

This will dry-up your mouth and make your gums crack and bleed in the morning. Bleeding gums is not the only problem that can arise from a dry mouth condition… The bad breath, tooth decay, and gingivitis are all common in mouth-breathers.

Saliva is an important part of a healthy mouth. Try to keep your mouth always moist by drinking plain water throughout the day. Use specially formulated mouthwash for dry mouth. Gargle and swish your teeth before you go to bed and in the morning. This should help reducing cracking and bleeding of your gums.

6. Recently quit smoking

If you recently stopped smoking and noticed that your gums started to bleed for no reason, this actually may be a good thing.

Cigarette smoke causes blood vessels to shrink and not function properly. And since you stopped smoking, the blood vessels in your gums are probably just coming back to life.

Don’t panic, gums supposed to bleed when they fight an infection. Most likely, you already have some form of gingivitis but didn’t experience bleeding gums symptoms until you quit smoking.

You could experiment with home remedies like swishing salty water in your mouth to remove the infection. But if you have smoked for a while, most likely this is not going to help.

Simple gingivitis in smokers (according to CDC) becomes advanced periodontitis much faster than in non-smokers. And the only way to find out what stage of gum disease you have is to visit a dentist.

Beginning stage of gingivitis is easily treated in a single session by a dental hygienist. However, the late stage of gum disease will require multiple visits to a dental office. Not only the treatment is more painful and more expensive, but you also may never fully recover from the disease.

Don’t procrastinate and call a dentist as soon as possible. You already took the first step by quitting smoking. Now take the second step and remedy your bleeding gums.

7. Vitamins C & K deficiency

Gums bleeding for no reason could be due to vitamin deficiency.

Vitamin “C” is a well-known nutrient and is very important for the gum and the skin health. Deficiency of the vitamin C may lead to a poor blood vessels structure and spontaneous bleeding of gums.

A few centuries ago, vitamin C deficiency (Scurvy) was known as Sailors Disease. On long sea voyages, they didn’t have enough fresh produce. And lack of vitamins led to bleeding gums, tooth loss, and death.

Today we have an abundance of fruits and vegetables rich in vitamin C, but they have to be consumed raw and fresh. Cooking or storing the produce for a long period of time can destroy much-needed vitamins.

Vitamin “K” is known as a blood-clotting agent. Without it, your gums could bleed non-stop for no reason. This is not very common and could happen if your body can not absorb vitamins from the intestinal tract.

You can get vitamin K from eating fresh leafy green vegetables like kale and spinach, broccoli and cauliflower. You can also get vitamin K from meats, eggs, and fish, but in smaller amounts.
