I have been experiencing persistent tooth pain and sensitivity, especially when eating hot or cold foods. Sometimes the pain becomes sharp or throbbing and I am worried the problem may be deeper than a simple cavity. I also noticed swelling around the gums and discomfort while chewing. I want to understand what actually causes a tooth to need root canal treatment and whether it can be prevented before the damage becomes severe.
At Ashford Dental Centre
we explain that a tooth usually requires root canal treatment when the inner pulp of the tooth becomes infected or inflamed. This commonly happens because of deep tooth decay, untreated cavities, cracked teeth, repeated dental procedures or dental trauma. When bacteria reach the tooth pulp, it can lead to severe pain, swelling, sensitivity and even abscess formation.
In some cases, patients may not feel pain immediately, but the infection can continue spreading inside the tooth. Root canal treatment helps remove the infected pulp, clean the canals and save the natural tooth from extraction. Seeking treatment early is important because delaying care may increase the risk of infection spreading to surrounding teeth and gums. Our dental team provides thorough examinations and personalized treatment plans to restore comfort and protect your long-term oral health.
