Dental Endodontic Root Canal Reamer

At some point, it could be required, and here’s why

If you’ve ever had a cavity or signs of gum disease, you might have heard of root canal. It can be the next step in healing tooth pain when decay has created an issue more serious than a filling alone can solve.

While a root canal is never at the top of anyone’s list of ways to spend an afternoon, it’s not as bad as you might think. Here’s what you should know.

What is a Root Canal?

A root canal is a procedure dentists use to put an end to nagging tooth pain. Root canals in teeth contain nerves and blood vessels that serve no purpose as an adult, beyond to sense heat and cold—leading to pain. The root canal procedure removes the nerve in an infected tooth to alleviate this pain.

Why the Procedure is Needed in Some Cases

If a tooth is so badly infected that you have serious pain that can’t otherwise be treated, your dentist will likely suggest a root canal. This option allows you to relieve the pain and remove the infection without completely removing the tooth, making it an appealing option to those who would prefer to keep their real teeth intact. Removing the tooth and replacing it with a dental implant is the other option, but this can also be more expensive–so many also choose the root canal for the cost-efficiency.

Signs You May Need a Root Canal

Extreme Tooth Sensitivity

While some sensitivity is normal in everyday life, especially if you’re eating something cold like ice cream, extreme tooth sensitivity that lasts even after you’ve fished eating the item is a big sign you might have an infection in the root canal that will need to be taken care of.


If you find some swelling near the tooth, or a bump, that is a sign that there might be an issue that will need to be corrected with a root canal.

Tooth Discolouration

It is common to find darkening of the teeth when a root canal issue is present. When it is happening in one particular tooth rather than all of them, it can be a sign that there is an issue with the nerve in that particular tooth, and a root canal may be necessary to repair the nerve damage.

Severe Tooth Decay

There comes a point where a tooth with a cavity has been ignored so long that it creates major damage, spreading down to the root and nerve of the tooth. When this happens, no amount of brushing or flossing will help. At this stage, a root canal will be the only option that saves the tooth.

Tooth/Mouth Pain

Persistent tooth pain that doesn’t come and go with eating is a big red flag that there might be something seriously wrong with the nerve of that particular tooth. If you do have continual issues eating or drinking without pain, it’s important to get to the dentist as soon as possible, as it may still be possible to fix the infection with antibiotics. If you wait too long it will reach a point where only a root canal can fix it.

Swollen Gums

If your gums are particularly swollen, it’s a sign that there could be a serious underlying issue in the nerve of your tooth. If you touch them and they hurt, this is an important sign that bigger issues could be at play.

How To Prevent the Need for a Root Canal

Preventing a root canal is similar to preventing all tooth issues—it starts at home with regular brushing and flossing after every meal. Seeing your dentist for regular cleanings ensures you catch problems like decay, cavities and swollen gums before they turn into a more serious issue with the nerve of your tooth. The best way to prevent the expense and bother of a root canal is to take great care of your teeth.

While the notion of a root canal has always been one that makes people shiver in fear, the reality is, they’re not all that bad at the end of the day. The pain of dealing with a tooth that needs a root canal is much more bothersome than that of the minor pain you might experience after the anesthetic wears off. Many patients describe the procedure as practically painless, similar to having a cavity filled.

A knowledgeable and kind dentist will make it as comfortable as possible. And once the pain is gone, it is gone for good and you will finally have relief.
