Experiencing a cracked tooth filling can be alarming, often leading to discomfort and uncertainty about the necessary steps to address it. This guide delves into the complexities surrounding this dental dilemma, offering expert insights on the causes, symptoms, and treatment options for both a cracked tooth filling and related dental issues.

The Onset of a Cracked Tooth Filling

Recognising the early signs of a cracked filling is crucial for prompt treatment. These symptoms might include sensitivity to hot or cold, a sharp pain when biting down, or a noticeable change in the tooth’s texture.

Understanding Dental Fillings and Their Vulnerabilities

Dental fillings, a staple in restorative dentistry, are designed to repair the damage primarily caused by tooth decay. Typically made from materials like amalgam, composite, porcelain, or gold, fillings restore the integrity and function of the tooth. However, these restorations are not impervious to wear and tear. Over time, fillings can weaken, making them susceptible to cracking. The onset of a cracked filling is a gradual process, often unnoticed until symptoms begin to surface.

Identifying the Early Signs of Cracked Teeth and Fillings

One of the first signs might be an unexplained sensitivity to hot or cold beverages and foods. This sensitivity occurs because the crack can expose the underlying dentine or even the tooth’s nerve, leading to discomfort.

Another early symptom is a sharp, sporadic pain when biting down or chewing. This pain may come and go, making it challenging to pinpoint the exact tooth. It’s often due to the movement of the cracked segments of the tooth or filling, which momentarily opens the crack and irritates the nerve inside.

The Role of Everyday Habits in the Development of Cracked Fillings

Everyday habits play a significant role in the integrity of dental fillings. Habits such as teeth grinding or clenching teeth (bruxism), chewing on hard objects like pens, ice, or hard candy, or using teeth as objects to open packages can all contribute to the weakening and eventual cracking of a filling. Even the natural ageing of a filling, combined with these habits, can expedite the process, leading to a cracked tooth or filling.

Recognising the Texture Changes

A physical change in the texture of the tooth might also indicate a problem. Running your tongue over the tooth and feeling a rough edge or a small gap where the filling meets the tooth can be a tell-tale sign of a crack. Monitoring these texture changes and seeking dental advice if any irregularities are noticed is essential.

Addressing a Broken Tooth Filling

When confronted with a broken filling, it’s not merely a matter of discomfort but also an oral health concern that warrants immediate attention. The breaking of a dental filling can expose the underlying damaged tooth to bacteria, increasing the risk of infection and further decay. It’s vital to treat this as an immediate dental emergency.

The first step in addressing a broken filling is to get an emergency dental appointment with your dental professional. Prompt action is key in preventing the situation from worsening. During the initial consultation, your dentist will examine the extent of the damage. They’ll determine whether the broken filling has led to additional tooth damage or if there’s a risk of infection.

Understanding the Treatment Options

The course of treatment for a broken filling depends on several factors, including the size of the original filling, the condition of the remaining tooth structure, and the presence of symptoms such as pain or sensitivity.

Filling Replacement: If the damage is confined to the filling itself, and the remaining tooth structure is sound, the dentist may replace the old filling with a new one.

Dental Crowns: In cases where the tooth has sustained significant damage, a dental crown may be recommended. Crowns are custom-made covers that mask the entire tooth, providing strength and protection.

Root Canal Therapy: A root canal procedure might be necessary if the break has exposed or damaged the tooth’s nerve. This treatment involves removing the damaged nerve, cleaning the inner sections of the tooth, and sealing it to prevent further issues.

Managing Pain and Discomfort

While waiting for your dental appointment, managing pain and discomfort is essential. Over-the-counter pain medications can be effective in reducing pain. It’s also advisable to avoid chewing on the side of the affected tooth and to stick to soft foods to prevent further damage.

Preventing Further Damage

Preventive measures are essential to avoid future instances of a cracked or chipped tooth. This includes maintaining good dental hygiene, avoiding biting on hard objects, and regular dental check-ups. These practices safeguard your fillings and contribute to overall dental health.

Surgical and Invasive Procedures

Sometimes, a cracked tooth filling may necessitate a surgical or invasive procedure. It’s crucial to understand that any invasive procedure carries risks; therefore, it’s important to discuss these with an appropriately qualified health practitioner. Depending on the severity of the tooth decay or damage, options may include a dental implant or more extensive root canal treatments.

The Role of Dental Crowns

Dental crowns often come into play when dealing with a cracked or broken dental filling. They serve as a protective cover, restoring the tooth’s shape, strength, and appearance.

Crowns are viable for preserving the tooth’s integrity, especially when the damage extends beyond a simple filling repair.

Root Canal: A Viable Solution



When a cracked tooth filling leads to significant damage to the tooth’s nerve, or if there is an onset of infection, a root canal treatment becomes a crucial intervention. This procedure, often misunderstood, is a pain-relieving treatment rather than a painful one. Its major goal is to save the tooth from extraction and preserve its functionality.

Demystifying the Root Canal Process

The root canal process involves several steps:

Diagnosis and X-rays:

Initially, the dentist will conduct a thorough examination, often using X-rays, to determine the extent of the damage and plan the treatment.


Local anaesthesia is administered to the affected area to ensure a comfortable treatment.

The dentist will create a minor opening in the top of the tooth to get to the damaged pulp (the soft inner tissue). This pulp, along with any decay and bacteria, is meticulously removed.

Cleaning and Shaping the Canals:

After removing the pulp, the inner chamber of the tooth and its canals are cleaned and shaped. This step is needed to prepare the tooth for the filling material.

Filling the Canals:

To seal the space, the cleaned canals are then filled with a biocompatible material, usually a rubber-like gutta-percha.

Restoration of the Tooth:

After the root canal, the tooth often requires a crown or filling to retrieve its strength and functionality, as it is more brittle post-treatment.


Dealing with a cracked tooth filling requires prompt and informed action. Understanding the causes, identifying the symptoms early, and seeking timely professional help can significantly impact the outcome. Regular dental visits and good oral hygiene are key preventative measures.
