Despite all of these antiseptic properties of Listerine, if you are wondering if you could use it for tooth pain, you may be over reaching. It may help in certain situations but not all.
Will Listerine kill a tooth infection?
Nowhere does it claim that this mouth rinse can fight or reduce teeth pain. It does remove germs but that may not necessarily give you the desired effect of being dental pain free. So if you are having pain from your tooth and you use this mouthwash, your mouth may feel fresh and that may be it.
The reason is that a tooth infection has usually spread beyond the outer surface of the tooth. A mouth rinse can rinse the outer enamel really well but it won't be able to get into the inside of the tooth where the infection is, especially if it has reached the bone.
Look at where the tooth infection is on this dental x ray. Do you see that big dark circle at the tip of the root? Only one tooth has this big dark circle and where it is located is in the bone. There is no way the Listerine will get into the bone and fight the infection so this makes it ineffective.
Will Listerine kill a tooth nerve?
Okay, so it doesn't work for pain but will the Listerine kill the tooth nerve at least?
Unfortunately the answer is still the same. The label does not say anything about rectifying nerve pain from your teeth. The answer to that is more physical because the nerve of the tooth is actually inside of the tooth. The nerves are not on the outside so you can't get to it. The only way to get to the nerve is to "open" up the tooth. There is no way you'll be able to open up your tooth yourself.
The tooth needs to be opened up for the mouth rinse to get to it. The only person who can open up your tooth like this would be a dentist such as any one of our LIC dentists. If you come to our long island city office, we'll be more than happy to help you with that!
Last but not least, are you still wondering what is the best mouthwash for a tooth infection, since it can't kill tooth pain nor can it kill the nerve, so what can it do?
Will a mouthwash kill a gum infection?
The answer would be, it depends because if the infection is coming from the tooth you may be out of luck such as in the situations listed above. Although if the infection is coming from the gums which surrounds the tooth, Listerine may be helpful. In fact, it may be the best mouthwash for a gum infection.
Gum infections can be caused by germs and also by plaque. Listerine does just that, reduces germs and plaque. If you have plaque and tartar sitting next to your gums, it can swell up like in the photo above. The mouth rinse can certainly help in controlling the swollen gums. It may not cure it completely but it can at least prevent it from getting even worse.
There is a caveat though, if your soft plaque has turned into hard plaque, it is called calculus. Calculus cannot be removed by Listerine. The hard calculus or hard tartar can only be removed by a professional dentist or dental hygienist. In that case, you would be required to schedule an appointment with our LIC office because the Listerine would not be able to help you.
Other scenarios where the mouth rinse can't help
Last but not least, another instance where the mouth rinse would not help would be if the infection turns into severe facial swelling from a tooth abscess. This is when your face just swells up so much that it looks like you gained weight.
Tooth infections causing swellings like this is a full blown abscess would need to be drained by a healthcare professional. A home remedy like Listerine cannot fight this type of facial swelling. If you happen to have this, you would need to go see a specialist, an oral surgeon, or go to your local emergency department of a hospital.
Verdict: Does mouthwash help with tooth pain?
Unfortunately, most mouthwash do not help with tooth pain nor will they stop a toothache. The reason is because Listerine is an antiseptic mouthwash and not an antibacterial mouthwash.
Antiseptic mouthwash. They don't require a prescription and their purpose is to help control plaque from building up. This means that the mouth rinse is used to prevention infections and not stop them.
Antibacterial mouthwash. They require a prescription but their purpose is to control an active infection. They may be used to prevent infections but typically they are only used after an infection has occurred.
So, if you were looking at Listerine as the best mouthwash for a toothache to get pain relief, you may be out of luck since it is an antiseptic rinse. Even though the ingredients within Listerine can fight bacteria, there is still no way for it to reach the nerve and offer any pain relief. Unfortunately, only your dentist will be able to give you pain relief from a toothache.
Listerine is one of the best mouthwash for fighting germs and plaque but it's ability to kill certain infections may be limited. When in doubt it is always best to schedule a dental check up with one of our dentists in long island city! If you can't get an appointment or won't be able to make it in, there are some home remedies that can temporarily help.
