The reason you should never brush your teeth after oral sex

Posted on

While you may get the urge to brush your teeth after oral sex, doctors warn it’s not safe.

When it comes to having sex, everyone knows that condoms are the way to go.

They offer a buffer for unwanted pregnancies, along with much-needed protection from any sexually transmitted infections a person may be susceptible to contracting.

However, oral sex is a different ballgame, so to speak. While dental dams are recommended by medical professionals they’re mostly a thing of the past – and aren’t much help for anyone practising oral sex on women. Thus, by and large, people tend to have oral sex without protection.

While that comes with its own set of risk factors, certain things can increase the risk of contracting an infection when practising oral sex. And shockingly, brushing your teeth is one of them.

After engaging in oral sex, many people beeline straight to the bathroom to do a proper scrub of their teeth and tongue – which we think is pretty goddamn fair, given oral sex is a particularly intimate act.

However, experts say that brushing your teeth is actually the worst thing you can do after giving oral sex, due to tiny microtears in your gums, caused by the bristles in the brush.

‘So what?’ you may ask. As GP Dr Prasanthi Purusothaman tells Body+Soul, “The risk is the abrasion causing cuts and minor bleeding of gums which acts as a possible opening for pathogenic bacteria and viruses and possible STIs to enter the bloodstream.”

Yep, think chlamydia, herpes, hepatitis A and B, syphilis, gonorrhoea and HIV. Any STI you could catch from sex will have an entry point straight into your gums.

And no, it doesn’t matter whether you’re having sex with a male or a female. If you’re going down on a man or a woman, the advice is clear: do not brush your teeth immediately after.

Medical advice aside, it’s pretty normal to want to wash out your mouth after oral sex, and water doesn’t always seem to cut it.

Fortunately, there are other things you can do to help feel fresh post-coitus.

“Rather than brushing, rinse the mouth with water only or try an antibacterial mouthwash,” says Dr Purusothaman. That will help to cleanse the mouth but won’t cause any cuts.

“Also spitting semen as soon as possible rather than letting it linger in the mouth,” Purusothaman says is always recommended practice.

The same rules apply if you’re a pre-sex brusher too. “The suggestion is no oral sex until at least 30 mins after brushing the teeth pre-oral sex,” she says.

So next time you’re planning on getting hot and heavy, go au naturale and leave the brushing for later that night, and buy a mouthwash for post-sex cleansing instead.

Everything You Need to Know About Oral Sex

Oral sex involves stimulating a partner’s erogenous zones with your mouth. Certain practices along with open communication may make the experience more pleasurable for both partners.

First things first

Rest assured that, even if it’s your first dive, chances are you’ll be fine — everyone starts somewhere!

But we want to make sure you’re more than fine, because life’s too short for oral that’s just meh.

After all, if you’re gonna go down, you should do it right.

Here’s what you need to know about the giving and getting of oral sex, plus all of the fun and even practical stuff in between.

Let’s set the record straight

Before getting down to nitty, let’s talk about the gritty.

Yes, oral sex is “real” sex

Forget what you heard from Clinton or anyone else about what sex is and isn’t. Penis-in-vagina sex is not the be-all-end-all of sex. Oral sex can be just as pleasurable — if not more so — than penetrative sex.

Your anatomy is unique

Vulvas and penises come in all shapes and sizes, so try not to spend any time worrying about how yours compares to someone else’s.

Vulvas rarely look like a perfectly juicy peach, and penises aren’t usually eggplant emoji-big or smooth.

Everyone has a smell of some kind

Scrub all you want, but you’ll still have some odor down there. It’s called your natural odor, and it’s fine.

That said, freshening up before oral sex is just the nice thing to do.

To keep things fresh:

  • Take a shower or bath, or at least use soap and water to wash your genital area.
  • Use a wet paper towel or unscented wipes if you need to freshen up on the fly.
  • Avoid perfumes or deodorants down there because they aren’t genital-friendly or necessary.
  • And everyone has a taste
  • You know whose genital juice tastes like cookies and cream? No one’s! We all have a taste down there.

As long as you’re healthy and on top of your hygiene, you should taste fine.

If you’re still worried about funky spunk, tweaking what you eat may improve the taste of your juice.

Avoid garlic, onions, asparagus, and cabbage, which reportedly make for a less-than-pleasant flavor.

To sweeten your sauce, try eating:

  • pineapple
  • papaya
  • nutmeg
  • cinnamon
  • celery

Pregnancy isn’t possible, but STIs are

There’s no risk of pregnancy from oral sex, but there is a very real risk of oral STIs.

Any skin-to-skin contact with the genitals can spread STIs. The same goes for contact with vaginal, penile, or anal secretions.

There’s also some risk of transmitting an STI to the fetus if you have oral sex during pregnancy.

STIs that can be transmitted through oral sex include:

  • gonorrhea
  • chlamydia
  • HSV-1 and HSV-2
  • syphilis
  • HPV
  • HIV

Some oral STIs don’t cause any symptoms, but if they do they may include:

  • sore throat
  • open sores or warts in or around the mouth and throat
  • swollen lymph nodes

Oral screening should be a regular part of your care plan

If you’re sexually active, you probably know that regular STI screening is important.

But did you know that you should be getting regular oral exams, too?

Your dentist can inspect your mouth to check for sores, lumps, or other abnormalities that could be a sign of an STI.

Oral exams are also used to check for signs of oral cancer. Certain strains of HPV can cause oral cancer.

You should see your doctor or dentist for at least one screening a year.

See your provider right away if you’re experiencing unusual oral symptoms or suspect that you’ve been exposed to an STI.

If your partner has a vulva
Common Qs
Do you really flick the clit? You can! Lightly flicking the clit with your tongue can be a nice way to mix things up and build pleasure. Think soft puppy tongue licking an ice cream cone — not woodpecker destroying a tree.

Should you insert your tongue or keep things penetration-free? That’s up to the person you’re going down on. Some people find the mere idea of being tongued hot AF, but fewer nerve endings in the opening means less sensation. If they like it then go to town.

What if they’re on their period or pregnant? If they consent and you’re cool with it, too, then go for it. Things can get messy, so focusing on the clit is probably the better way to go. Know that blood can have an odor and a metallic taste. A dental dam can help if you’re squeamish.

Technique
Try this:

  • With your tongue flat, lap long strokes over their underwear until you get the fabric — and them — wet.
  • When they’re ready for tongue-to-skin action, spend a little time licking the fleshy mound above the clit. Show the inner thighs some love, too.
  • Lay your wet tongue flat at the bottom of their vulva and lick your way up. Repeat.
  • Flex your tongue and use the tip to lick tiny circles over the clitoral hood — the little flap of skin over the clit.
  • Use your fingers to gently pull the hood upward so you can focus the tip of your flexed tongue on the clit. Start with light pressure and speed and gradually ramp things up.
  • When you get into a groove that they love, keep at it to take them over the edge.
  • Positions
  • With a little determination and imagination, you can turn pretty much any penetrative sex position into an oral sex position.

But to save you the neck cramps, we recommend these oral-friendly positions:

  • Lie Back and Enjoy. Have them lie on their back with a pillow under their butt and legs apart while you lie or kneel in between with your face in the muff of it all.
  • Control Freak. Lie on your back and have them straddle your face while facing you so they control the moves and pressure — and watch you work for it.
  • Almost 69. They get to straddle your face again, only this time they’re facing your main attraction and can return the favor in the way of some 69 action.
  • Safety and cleanup
  • The best barrier method you can use when giving oral to someone with a vulva is a dental dam. This is a thin latex barrier that you place over the vulva.

You can order dental dams online or use a condom to create an alternative.

Do a quick wash up before and after oral sex with soap and water or gentle wipes and you’re both good to go.

If your partner has a penis
Common Qs
What should you do if they’re uncircumcised? There’s not much difference in technique as far as circumcised vs. uncircumcised. If you start off with a hand job, let the foreskin move up and down with your hand. When you’re ready to get licky with it, gently pull the foreskin downward to expose the head.

Do you have to deep throat? Nope, not unless you want to. Not going deep isn’t going to make or break an oral sesh. You can totally fake it by placing the tip of your tongue on the roof of your mouth and sucking as much as you’d like without an unexpected gag.

Should you spit, swallow, or keep ejaculate out of the mouth entirely? That’s something to discuss with your partner beforehand, but you don’t ever have to do anything you don’t want to do. If it’s a visual turn on for your partner, having them finish on your closed lips or chin — or wherever you’re comfortable with — should do the trick.

Technique
Give these moves a try:

  • Start by using the tip of your tongue up and down the base of their shaft, pausing to circle it around their head.
  • Show the underside of the shaft some love and then lightly flick the frenulum — the little wrinkle of skin where the shaft joins the head — with the tip of your tongue.
  • Lap up the entire length and repeat. Bonus points if you let them hear how much you enjoy doing it.
  • Hold the base of their shaft and take the rest in your mouth, then slowly slide up and down while sucking lightly.
  • Pick up the pace as their pleasure builds.

Positions
Again, with some imagination you can get your blow on in just about any position. Try giving these a go:

  • Open Wide. Lie on your bed with your with head near the edge and open wide while they stand with their head facing your feet and penis over your mouth.
  • Sit and Suck. One chair, two ways. Have them sit on the chair while you kneel before them and take matters into your mouth, or you do the sitting while they stand with their legs on either side of the chair while you lean in.
  • Laidback Lovin’. By far the most comfortable BJ position ever and perfect for those lazy morning blow jobs. While they’re on their back, lie on your side and use their torso as a pillow while you use your mouth and hands.

Safety and cleanup
We’ve got two words for you: flavored condoms. Seriously, if you’re going for the safe blow job, flavored condoms reduce your risk for STIs while giving you something tasty to suck on.

As for cleanup, a shower before and a wipe up after does the trick.
