A root canal procedure is highly effective in treating infected or damaged teeth. However, proper aftercare is essential to prevent reinfection, protect your restored tooth, and ensure long-term oral health.
At McLevin Dental in Scarborough, we focus on helping patients not only undergo successful root canal treatment but also maintain their results. This guide provides practical advice on avoiding reinfection post root canal procedure to keep your smile healthy and strong.
Why Reinfection Can Occur
Failure to maintain proper oral hygiene after the procedure
A cracked or damaged filling or crown that exposes the tooth
Bacteria entering through new cavities or gum disease
Delaying placement of the permanent crown, which leaves the tooth vulnerable
Key Steps to Avoid Reinfection
?? Get the Permanent Crown Promptly
A root canal-treated tooth is more brittle and vulnerable.
Delaying the placement of a permanent crown increases the risk of cracks or leaks that can allow bacteria back in.
Schedule your crown appointment within 12 weeks after the root canal, or as advised by your dentist.
?? Maintain Excellent Oral Hygiene
Brush twice daily with fluoride toothpaste to remove plaque.
Floss daily to prevent bacteria buildup between teeth and near the gums.
Use an alcohol-free antibacterial mouthwash to reduce bacteria.
?? Be Gentle with the Treated Tooth (Until Crowned)
Chew on the opposite side of your mouth until the crown is placed.
Avoid hard, crunchy, or sticky foods that could fracture the temporary filling.
?? Treat Bruxism if Present
Teeth grinding (bruxism) places excessive stress on a root canal-treated tooth.
Wear a custom night guard if you clench or grind during sleep.
Foods to Eat for Tooth Protection
Soft foods: Scrambled eggs, yogurt, mashed potatoes, smoothies (without straws), pasta.
Avoid temporarily: Nuts, popcorn, ice, hard candy, crusty bread, and chewy candies until the crown is in place.

Contact McLevin Dental immediately if you notice:
Persistent or worsening pain after the root canal
