Is sperm good for teeth and gums?

Is sperm good for your teeth and gums? Obviously a debatable question! We don’t know how this question started and who thought about it first, or why, but let’s focus on scientific facts here. Even though there has not been evidence to back up this claim, every once in a while it comes up.

It does make you wonder. If you think about fertility, it makes sense that sperm has nutrients to help the embryo grow at those beginning stages. But does it have the same effect when it comes to oral health?

Let’s talk about it: is sperm really good for teeth and gums?

Well, not exactly!

Ok, let’s get spunky. People use semen and sperm interchangeably, but they are different. It is a common mistake and it doesn’t cause a problem in our context, but we are here to give you the correct information. What we call sperm here is actually semen.

Semen or the seminal fluid contains sperm and has other ingredients such as lactic acid, fructose, glucose, citrate, calcium, magnesium, potassium, zinc, and protein. It sounds nutritious, doesn’t it? However, the amount of these minerals is not exactly sufficient enough for a grown body to cover its needed daily nutritional intake.

Myths about sperm for teeth and gums

To be honest with you, there has not been a single piece of evidence to pinpoint when in history the myths about sperm started. It is still a mystery and continues to bewilder scientists as well. Some people have shared their experiences and claim these are not myths, but it still has the medical community divided on whether sperm is good for your teeth and gums or not. But there are some reoccurring myths when it comes to semen and sperm.

We will go through them and fact-check them. So, take your “head” out of the gutter, and let’s go through some of the most common myths about semen.

Can sperm help prevent cavities?

No! Let us explain. If you have already searched about this online, you might have seen that many websites claim that the American Dental Association (ADA) has published an article proving this to be true. But so far, it has been removed and it is nowhere to be found. But here is the thing when you think about all the minerals and vitamins in semen you might say well how harmful can it be?

Of course, it is not harmful but does not think it is so beneficial to forget about your toothpaste and use semen instead. Let’s put it this way, sperm or more accurately semen is not good nor bad for your teeth and there has not been any evidence of it either.

Can semen prevent tooth decay?

Well, basically the same answer for cavity can go here. No, semen does not prevent tooth decay. Semen’s pH is between 7.2 to 7.8 and it is actually slightly alkaline. This would not cause problems for our teeth, but if we are talking about infection, that is a whole different story and we will get to it. 

Are vaginal fluids good for teeth?

We can not forget about the ladies. So we talked about semen being a bit alkaline. It might be your question too! What is the pH of vaginal fluids then? Hate to tell you this, but those juices coming from the vagina are more on the acidic side. The normal vaginal pH is between 3.8 to 5.0. Giving your partner the Australian kiss is not going to harm your teeth. Just a quick rinse with water after, and you are good to go.

Is sperm good for gums?

No! There is no proof that exposure to semen, or sperm, is good for gums. But as we mentioned above, there is a risk of infection. No harm in sucking the lollipop, but if you have recently been to a dental clinic and got some work done you better be careful. Dental work such as tooth extraction, wisdom tooth extraction, or deep teeth cleaning comes with open wounds and minor cuts. There is a higher risk of infection with those procedures if you have gotten them and they are not healed completely.

Does semen have protein?

Yes! This is a fact and is scientifically proven. Remember we can not compare the amount of protein in sperm with an egg. But based a study done in 2013 concluded that protein in semen is 252 mg per ejaculation on average.

Sperm in mouth side effects

The most dangerous side effect of sperm in the mouth we can say is sexually transmitted infections, also called STIs. Most people might not practice safe sex when it comes to oral sex due to believing it is not crucial, which in fact, it is highly necessary. It does not matter if you know your sexual partner or if it is a one-night stand. Better safe than sorry, right?

Even if your partner does not have any STIs if you have any cold sores or ulcers in your mouth the risk factor of getting oral infections is higher. On a related note, it is said to brush and use dental floss on your teeth 2 hours before and after the actual oral-genital contact. This is because of any nicks and cuts that might happen when you brush or floss your teeth.

Some people, whether a man or a woman, can have an allergic reaction to semen or sperm. This is because of the protein present in sperm and semen. The symptoms could be redness, swelling, itching, and dryness in the mouth. In severe cases could even cause difficulty in breathing.

Last but not least, we have mentioned in one of our previous articles that after a tooth extraction or deep teeth cleaning you better not go to the candy shop and lick any lollipops. This puts you at more risk of a bacterial infection or viral and might even lead to periodontal disease.

So next time you want to have some fun “eating out” better have some safety measures.

A safe visit down under

Now, this brings us to how to practice safe oral sex. Practicing safe oral sex has a direct effect on your oral health and dental health. Most people do not care about oral-genital contact and believe STIs are only transferred through sexual intercourse. There are a few ways that you can have a safe visit down under not only to protect yourself but also your sexual partner as well. One of the best ways to do so is to use condoms. There are also dental dams. If the toy you carry is a banana, condoms are the easiest and safest when it comes to safe sex practice. But if it is a honey pot you carry, better cover it up with a dental dam. What is a dental dam you ask? It is a thin sheet of latex that is mostly used in dentistry. It is body safe and since it is a sheet, it can be used to cover the vagina to practice safe oral sex.
