Ever noticed a dark shadow lurking under your dental crown when you flash your smile in the mirror? It’s a common issue that can leave many feeling self-conscious and anxious. But what exactly causes this discolouration, and more importantly, how can it be addressed?
Understanding Dental Crowns
Dental crowns, a crucial aspect of oral care, demand your understanding.
Why Are Dental Crowns Important?
Dental crowns serve as protective covers for your damaged teeth. They enhance the tooth’s appearance, shape, alignment, and overall dental health.
How Do Dental Crowns Work?
The working principle of dental crowns is pretty straightforward. They encase the entire visible part of your tooth or dental implant. Think of it as a cap placed on your tooth, providing strength and protection from further damage.
Causes of a Black or Discoloured Tooth under a Crown
Exposed Metal Filling
A black tooth under a crown might be due to an exposed metal filling. When light reflects off the metal, it gives a dark shadow which can appear as discolouration to the naked eye. For instance, imagine catching a glimpse of your old silver fillings in the mirror.
Tooth Decay
Tooth decay doesn’t stop just because you’ve got a crown. It sneaks up, often undetected until it’s too late. Bacteria can still reach the natural tooth underneath and continue their destructive work, potentially causing discolouration.
Intrinsic Staining
Intrinsic staining is another culprit. These are stains that occur within the tooth itself, rather than on the surface. They’re similar to how tea or coffee stains seep into your favourite white mug over time.
Pulp Necrosis
Pulp necrosis, essentially death of the tooth’s pulp tissue, often results in a grey or black discolouration. This is akin to plants wilting and turning brown when they don’t get enough water or nutrients.
The Implications of a Black Tooth under the Crown
A blackened tooth under a crown may seem like just an aesthetic issue, but it carries implications that extend beyond mere appearance.
Pain and Sensitivity
When your tooth beneath the crown turns black, you may experience discomfort. This discolouration often indicates decay or damage deep within the tooth, causing sensitivity to hot or cold foods and drinks. It’s not just about bearing the pain; this sensitivity can hint at more severe underlying issues.
Risk of Infection
A blackened tooth signifies potential infection risks. Bacteria might have infiltrated your tooth, leading to decay and discolouration. If left unchecked, it could develop into an abscess – a painful infection at the root tip that can spread to other parts of your body.
Aesthetic Concerns
On top of health concerns, a blackened tooth under a crown presents aesthetic problems too. Visibility when you talk or smile, it can affect your self-confidence and social interactions. And yes, people notice – a healthy smile makes a big difference in personal relationships and professional settings alike.
How to Prevent Tooth Discolouration under a Crown
Preventing tooth discolouration beneath a crown involves several important steps.
Maintaining Proper Dental Hygiene
Brush twice daily, floss regularly and incorporate mouthwash into your routine. For example, using fluoride toothpaste can help prevent decay, keeping your teeth white and healthy under the crown.
Regular Dental Check-ups
Schedule dental check-ups at least twice a year. Remember, these visits aren’t just for cleaning; they’re also an opportunity for the dentist to spot potential issues, such as decay or damage that could lead to discolouration.
Utilizing Nightguards for Bruxism
If you grind your teeth at night – a condition known as bruxism – consider using a nightguard. By protecting your teeth from the pressure of grinding, you’re also safeguarding against possible cracks that could expose the tooth beneath the crown.
Avoiding Hard Foods and Habits
Limit hard foods and avoid habits like nail-biting or pen-chewing. These actions put extra pressure on crowns which can lead to fractures in the material over time, increasing the risk of discolouration underneath.
Is it Normal for the Tooth to Get Black Under the Crown After a Root Canal?
Experiencing a blackened tooth under a crown post-root canal isn’t uncommon. Tooth discolouration often stems from changes in the tooth’s internal structure, primarily after procedures like root canals. During such treatments, dentists remove the tooth’s nerve and blood supply, causing it to darken over time.
But, this doesn’t necessarily mean you’re facing severe dental issues. It’s important to remember every individual’s response to dental procedures varies; some might see discolouration while others won’t. Regular dental check-ups ensure your dentist can monitor any changes and intervene if necessary.
Also, a darkened tooth can be due to other reasons apart from root canal treatment. For instance, remnants of previous fillings or decayed material left behind could contribute to a dark appearance under the crown. This scenario demands immediate attention from your dentist.
