Cavities are one of the most typical oral conditions, but what does a decayed tooth look like? Identifying them depends mainly on the severity of the hole and where it is in your mouth. They are classically not noticeable until they have caused widespread harm.
Still, there are ways to avoid decay and even apply suitable treatment if they are discovered in time. Read on to learn the answer: what does a decayed tooth look like? And determine if you have one.
What does a decayed tooth look like? Main symptoms
A cavity is a hole that forms in your tooth due to tooth decay. It occurs when the enamel, the hard outer layer of the tooth, is damaged by acids produced by bacteria in the mouth. These bacteria feed on sugars from food and drinks, leading to plaque buildup.
Over time, the acids erode the enamel, creating what is known as a cavity. If not treated, cavities can grow larger and affect deeper layers of the tooth, causing pain and infection and potentially leading to tooth loss. Regular dental care can help prevent cavities from forming.
Since decay is a fairly common oral condition, the answer to the question, “What does a decayed tooth look like?” is essential. In most cases, decay is not recognized until there is advanced deterioration.
Therefore, below, we reveal some signs to answer the question: what does a decayed tooth look like?

1. Dental sensitivity
When caries form, sensitivity can develop, fluctuating from minor to severe. One of the most regular signs of sensitivity is discomfort or pain with cold or hot foods.
2. Pain when consuming certain foods or drinks
Dental sensitivity is perceived after consuming some specific foods or beverages. Sweets are responsible for triggering the most intense toothaches. If you have pain, visit our clinic to rule out cavities.
3. Toothache with pressure
If you feel sharp tooth pain when you press or bite, it is probably due to caries or other dental issues. Consult the professionals to determine the cause of the pain.
4. Pain in teeth and other parts of the mouth
In the first stage of these lesions, you may feel pain or even not feel it, which prevents their detection. However, they can cause permanent toothaches if not discovered in time.
5. Cracks or holes
When enamel erosion starts, it is possible to feel or see small holes in the teeth where they are lodged. In this sense, if you detect decayed areas of this type, visit real professionals.
6. Stains or discoloration
It is another of the visible signs of a lesion. Usually, the stains are brown, black, or sometimes bright white. Although dental stains can be natural, if you are concerned, request a check-up with one of our professionals.
7. Bad taste and bad breath
Decay is an infected area that collects food particles and becomes a bacterial culture. Consequently, bad taste and insistent lousy breath clearly show their incidence.
They are nearly impossible to spot in their early phases. They begin with a white or pallid appearance on the tooth, but as the problem progresses, their color becomes brown or black. Though, in most cases, no alarms can confirm the formation of decay.
In conclusion, understanding what does a decayed tooth look like is essential for maintaining good dental health. Early signs of tooth decay can include white spots or discoloration on the enamel, which may gradually turn brown or black as the decay progresses. As the cavity develops, small holes may appear.
But what exactly is a cavity? A cavity is a hole in the tooth caused by decay, which results from the breakdown of tooth enamel due to plaque and bacteria. If left untreated, cavities can worsen, leading to more severe damage to the tooth and even tooth loss.
In its advanced stages, a cavity may appear as larger holes or severe damage to the tooth’s structure, often accompanied by pain and sensitivity. Thankfully, cavities can be treated effectively. Early-stage cavities are treated with fillings, while more advanced cases might require a root canal or extraction.
If you notice tooth decay, visit your dentist immediately to prevent further damage. Regular check-ups and good oral hygiene can help keep your teeth healthy and avoid the need for more invasive treatments.
When should you visit the specialist for a cavity?
Now, you know the answer: what does a decayed tooth look like? How do you know if you have a decay? Decayed areas can be identified through an X-ray. Visiting dental health professionals is crucial for your well-being.
Many people delay dental visits, so they usually detect enamel erosion in advanced stages. If you feel acute pain in a tooth, remember to visit Rubio Dental Group to check for any signs of enamel erosion.
Generally, patients endure pain until it is practically intolerable and go to the dentist when the holes are advanced. In these cases, they have already reached the nerve; therefore, the tooth loses vitality.
In this sense, a root canal must be performed, which is expensive and invasive, unlike a filling. For this reason, it is indispensable to undergo dental revisions and cleanings at least twice a year.
