Root-treated teeth, while strengthened by the treatment, can still be susceptible to breakage due to various factors. One significant reason is the removal of the tooth's nerve and blood supply during the root canal procedure, which can lead to the tooth becoming more brittle over time. Additionally, the loss of tooth structure during the initial decay or damage that necessitated the root canal can weaken the tooth's overall integrity. Without adequate support, such as a dental crown or filling, the tooth may be more prone to fractures from chewing forces or accidental trauma. Furthermore, if the tooth is not properly restored after the root canal treatment or if there are underlying issues like untreated decay or inadequate root canal filling, it can compromise the tooth's strength and increase the risk of breakage. Regular dental check-ups and proper oral hygiene, along with timely restoration of root-treated teeth, are essential for preventing complications and maintaining long-term dental health.
