The tooth had a crack extending through the middle and could not be saved. Posterior teeth with large fillings or root canal treatment are at a higher risk of developing significant cracks. This risk can often be reduced by placing a protective crown.
The picture shows an old amalgam (silver mercury) filling with a fracture affecting the cusp of the tooth. Unlike modern white composite fillings, amalgam does not bond directly to the tooth structure. As a result, the tooth can become weakened over time and more susceptible to cracks and fractures.

Dr Alfie Chan, an experience and trusted Newbury dentist, regularly diagnoses and treats cracked teeth, helping patients preserve their natural smiles whenever possible. Cracked teeth are a common dental problem that can affect patients of all ages. At The Rectory Dental Clinic, Cracks can vary from tiny surface lines in the enamel to severe fractures that extend deep into the tooth root.
Cracked teeth may develop for several reasons, including teeth grinding (bruxism), biting hard foods, accidental trauma, large fillings that weaken the tooth structure, or the natural ageing process. The back teeth, particularly molars, are most commonly affected because they absorb the greatest chewing forces. Symptoms can include pain when biting, sensitivity to hot or cold foods and drinks, or intermittent discomfort that can be difficult to pinpoint.
At our Newbury dental practice, treatment depends on the size, depth, and location of the crack. Minor craze lines that affect only the enamel often require no treatment other than monitoring during routine dental examinations. More significant cracks may be repaired using a filling or, more commonly, a dental crown, which helps strengthen the tooth and prevent the fracture from worsening. If the crack extends into the pulp where the nerve is located, root canal treatment may be necessary before placing a crown. Early diagnosis greatly improves the chances of saving the tooth.
Some cracks carry a less favourable prognosis. A vertical crack running through the centre of the tooth and extending below the gum line, often referred to as a split tooth or vertical root fracture, may not be repairable. In these situations, extraction may be the most appropriate treatment to prevent infection and further damage to the surrounding bone and tissues.
Following extraction, Dr Alfie Chan can discuss tooth replacement options, including dental bridges and dental implants. Many patients choose dental implants because they help preserve jawbone and do not affect neighbouring teeth. As an experienced provider of dentistry in Newbury, Dr Alfie Chan focuses on early detection and preventative care, giving patients the best opportunity to retain their natural teeth for as long as possible.
