Tooth pain after root canal when biting is alarming. It may indicate an underlying issue such as a crack in the tooth due to reduced blood supply or an over-filling. In both cases, an individual may experience pain when biting. It’s best to consult the dentist who performed the procedure to know more about the fundamental cause. Let’s discuss the possibilities, the remedies, and the treatment. 

At’s the Reason Behind Tooth Pain After Root Canal When Biting?

Slight discomfort or pain after a root canal is normal. However, if it persists, it becomes a cause of concern. Determining the principal reason behind tooth pain after a root canal may be tricky as many factors influence the condition. In this article, we will discuss the possibilities that may inflict pain when biting after a root canal:

  1. BRITTLE TOOTH: The purpose of the pulp is to provide nourishment to the tooth to keep it strong and durable. Root canals focus on removing the infected pulp to eradicate the infection. However, the pulp’s disposal comes at the cost of the tooth’s sturdiness. The main reason behind pain when biting after a root canal is that the tooth becomes brittle due to lack of nourishment. 
  1. EXCESSIVE FILLING: Upon occlusion, the tooth with an excessive filling may cause extra pressure on itself as well as the opposite tooth resulting in pain. The effects of over-filling are noticed soon after the anesthesia wears off, and contacting the dentist as soon as possible is recommended. 
  1. INJURY TO THE TISSUES: In rare cases, the sharp instruments used during the procedure may cause injury to the surrounding tissues that result in pain. It’s temporary as the discomfort will subside itself once the tissues heal. 

The key to keeping tooth pain while eating at a distance includes avoiding hard and crunchy food items as they can exert pressure on the freshly operated teeth increasing the chances of complications. 

What Are the Home Remedies?

Often, the dentist may be unavailable or have a full slot of appointments. In such scenarios, home remedies come in handy to relieve the pain. Try these prophylactic methods to get relief from tooth pain when biting after a root canal. 

  1. SALTWATER: Several research studies have been carried out to analyze the correlation between salt and toothaches. Salt contains anti-inflammatory and healing properties which help with pain and provides temporary relief. Take a warm glass of water and mix one tablespoon of salt and gargle properly. 
  2. PEPPERMINT: Peppermint tea bags are particularly useful in treating toothaches. It contains numbing properties which deal with the pain effectively. Simply place a peppermint teabag at the site of pain and let it do the work. The effectiveness can multiply if the tea bag is cold. 
  1. CLOVE: The herb is especially rich in eugenol, a proven natural anesthetic. Therefore, applying clove oil may numb the area and take away pain sensation giving relief to the suffering individual. 
  1. VANILLA EXTRACT: It may sound odd, but vanilla extract can be extremely useful in treating aches. Take a small amount on a cotton ball and dab it on the tooth where it hurts. It’s because the extract contains analgesic moieties that minimize the pain. 
  1. COLD-COMPRESS: Using a cold compress may reduce inflammation, thereby subsiding pain. Either put an ice bag in the freezer or put ice in a cloth and apply it to the affected area.

What Will the Dentist Do?

It’s crucial to book a dentist’s appointment when an individual feels any pain sensation after a root canal. The dentist will closely examine the origin of pain sensations and establish the reason. For instance, if the toothache is because of over-filling, the dentist will file the area to level it. However, if the cause of toothache is due to a cracked or brittle tooth, the dentist will start with an x-ray to investigate and further proceed with the restoration of the crown to deal with the brittle or cracked tooth. 

Tooth pain after root canal when biting can be managed by home remedies and over-the-counter medications, but it’s vital to get a permanent fix to avoid agony and frustration throughout the days. Once you’ve been to the dentist and the basic reason has been eliminated, you’ll start feeling lighter and better. 

What Should Be Done to Prevent the Need for a Root Canal? 

Instead of dealing with pain after root canals, isn’t the idea of taking preventive measures to eliminate the probability of a root canal altogether fascinating? Oral infections are considered inevitable, yet there’s a very high prospect that root canals can be prevented significantly if proper oral hygiene measures are adopted. 

  1. Brush twice a day: It’s no secret that brushing twice a day is recommended to keep root canals away and dental ailments.
  2. Floss regularly: Not many are aware of the benefits of flossing. It manages to reach nooks and crevices that the toothbrush cannot locate. Consequently, any residual food which may lead to bacterial growth and ultimately an infection is removed.
  3. Visit a dentist frequently: It’s important to make bi-annual visits to the dentist’s office for a complete dental checkup. In this way, any undetected cavities which may pave the way for bacterial colonization are eliminated, and the risk of infection is minimized.
  4. Only use teeth for the intended purpose: Countless people have become fond of opening bottle caps from their teeth. While it may look cool (to some), it should be discouraged as the risk of the teeth being damaged is significantly high. Any injury makes a place for bacterial infestation, which eventually results in an infection.


Tooth pain after a root canal when biting can cause concern, but it’s all a piece of cake once the reason is determined. Never ignore the pain or let it slide. Always take care of your oral health to eliminate any likelihood of a root canal surgery if you’re scared of it.
