Diamond Smiles: Real Talk on Dental Health

Health & Fitness


Pain when biting or applying pressure to a tooth can be confusing—and alarming. Is it a cavity? A cracked tooth? Or a sign that something deeper, like a root canal infection, is developing?


In this episode of Diamond Smiles, the dentists at Burwood Diamond Dental unpack one of the most common (and misunderstood) dental complaints: tooth pain under pressure. We explore how the inner pulp of the tooth reacts to inflammation, why pain may worsen when chewing, and how previous dental work like fillings or root canal treatments can sometimes contribute to lingering discomfort.


Midway through the episode, listeners are guided to a detailed clinical explanation available on the Burwood Diamond Dental website visit here where pressure-related tooth pain and root canal symptoms are broken down step by step, including when to seek urgent care versus when monitoring is appropriate.
