What is Tooth Decay and How Do I Know If I Have It?
Tooth decay is one of the most common dental concerns in the world, but it’s important to know that it is highly treatable, especially when caught early. In simple terms, tooth decay is the process where the hard outer surface of your tooth, the enamel, is damaged. This damage is caused by acids produced by bacteria in your mouth. For a more detailed scientific overview, you can read about What is Tooth Decay, but our goal here is to give you a clear, calm understanding of what might be happening and how we can help.
A Simple Explanation of How Cavities Form
The process begins with plaque, a sticky film of bacteria that constantly forms on your teeth. When you consume sugary foods or drinks, the bacteria in plaque feed on these sugars and produce acids as a waste product. These acids attack your tooth enamel, removing essential minerals and weakening it. Over time, this acid erosion creates a small hole, or cavity, which will grow larger if left untreated.
Common Signs and Symptoms of Tooth Decay
While decay can sometimes be silent, there are several signs you can look out for. Recognising them early can lead to a simpler, more comfortable treatment. Symptoms often progress and can include:
- Sensitivity: A short, sharp pain when eating or drinking something sweet, hot, or cold.
- Staining: Brown, black, or white stains appearing on the surface of your tooth.
- Visible Holes or Pits: You may be able to see or feel a small hole in your tooth.
- Pain: A persistent toothache or sharp pain when you bite down on food.
Why You Might Not Feel Pain (And Still Need a Dentist)
One of the most common questions we hear is, “If I don’t have pain, do I still have a problem?” The answer is often yes. Your tooth’s enamel has no nerves, so the initial stages of decay are completely painless. Pain only begins when the decay has progressed deeper into the tooth, reaching the sensitive dentine layer or the central pulp. This is why regular check-ups with a skilled decay dentist are so crucial. We can identify and treat decay long before it causes you any discomfort, ensuring your treatment is as minimal and stress-free as possible. Seeking early care is always the best path to lasting oral health.
The 5 Stages of Tooth Decay: From Early Warning to Urgent Problem
Tooth decay is not a sudden event but a progressive condition. Understanding how a small issue can develop into a serious problem helps clarify why different treatments are recommended at different times. By catching decay early, you and your dentist can prevent pain and more complex procedures. Each stage requires a specific, caring approach to restore your tooth to health.
Stage 1 & 2: White Spots and Enamel Decay
The very first sign of decay is often a small, chalky white spot on your tooth. This indicates demineralisation, where the hard enamel has lost essential minerals. At this early stage, the damage is often reversible with fluoride treatments and excellent oral hygiene. However, if the process continues, the enamel will break down, creating a cavity. Once this happens, the damage is permanent and a filling is needed to repair the tooth.
Stage 3: Dentin Decay
Once decay passes through the enamel, it reaches the softer layer beneath called dentin. Because dentin is less dense and contains tiny tubes leading towards the tooth’s nerve, decay spreads much faster here. This is typically when you might start to feel sensitivity to hot, cold, or sweet foods. An experienced decay dentist will treat this with a durable filling or, if the cavity is large, a dental crown to protect the remaining tooth structure.
Stage 4 & 5: Pulp Involvement and Abscess
This is the critical stage where the decay reaches the pulp-the innermost part of your tooth containing nerves and blood vessels. The bacteria cause an infection, leading to inflammation and often, a severe and persistent toothache. At this point, a filling is no longer sufficient. Root canal treatment is required to carefully remove the infected pulp, clean the inside of the tooth, and prevent its loss. If left untreated, the infection can form a painful abscess at the root tip, which can cause swelling and pose a risk to your overall health. If you are experiencing severe toothache or suspect an infection, it’s crucial to seek urgent care from a qualified decay dentist promptly.

Your Visit to the Dentist: A Calm and Gentle Diagnosis
We understand that visiting the dentist, especially when you suspect a problem like tooth decay, can feel daunting. Our primary goal is to provide a calm, stress-free experience. Think of this first appointment not as a treatment, but as a caring and thorough investigation. We are your partners in oral health, and our first step is simply to understand what’s happening so we can find the best path back to a healthy, comfortable smile.
The Gentle Visual Examination and Discussion
Your appointment will begin with a simple, gentle conversation. We’ll listen carefully to any concerns you have, whether it’s sensitivity, a dull ache, or something you’ve noticed in the mirror. Your decay dentist will then perform a careful visual check, looking for the subtle signs of decay like discolouration or changes in tooth enamel. This is a completely painless process, and we promise that no treatment will ever be performed without your full understanding and consent.
Using X-rays to See Beneath the Surface
Often, decay can hide where the eye can’t see-between teeth or beneath an old filling. To get a complete picture, we use dental X-rays. This is a quick and painless diagnostic tool that provides vital information about your oral health. These images allow us to see the precise extent of any decay, which helps us understand its progression, as detailed in resources like The 5 Stages of Tooth Decay from the American Dental Association. This ensures your diagnosis is accurate and the treatment plan is perfectly tailored to your needs.
Creating Your Personalised Treatment Plan
Once we have all the information, your dentist will sit down with you and clearly explain their findings. Using your X-rays and examination notes, they will show you exactly what is happening and discuss all available treatment options. We believe in complete transparency, so we will cover the benefits of each approach, the steps involved, and the associated costs. Ultimately, you are in control. We provide the expert guidance; you make the final decision, ensuring you feel confident and comfortable with the agreed plan.
Modern Treatments for Tooth Decay: Saving Your Smile
When you’re facing tooth decay, our primary goals are to ease your discomfort and, most importantly, to save your natural tooth. Thankfully, modern dentistry offers several highly effective, comfortable treatments designed to restore your oral health and bring back your peace of mind. Your dentist will always recommend the most conservative option that fully resolves the issue while preserving as much of your healthy tooth structure as possible.
Dental Fillings: The Standard Repair for Cavities
For small to moderate cavities, a dental filling is the most common and effective solution. The process is straightforward and designed entirely for your comfort. After completely numbing the area with a local anaesthetic, your dentist will gently remove the decayed portion of the tooth. The clean space is then filled with a durable material. We use modern, tooth-coloured composite resins that not only blend seamlessly with your natural smile but also bond directly to the tooth, often requiring less removal of healthy tooth structure.
Dental Crowns: Protecting and Strengthening Damaged Teeth
When decay has weakened a significant part of the tooth, a simple filling may not provide enough strength for the long term. In these cases, a dental crown acts as a custom-made protective cap. It covers the entire visible portion of the tooth, restoring its original shape, size, and strength. A crown doesn’t just repair the damage; it shields the vulnerable tooth from the pressures of chewing, preventing fractures and further harm. It’s a comprehensive solution for both function and aesthetics.
Root Canal Treatment: The Solution for Deep Decay
If decay reaches the innermost part of your tooth-the delicate pulp-it can lead to a severe infection and intense pain. This is where root canal treatment becomes the hero of the story, saving a tooth that might otherwise be lost. Contrary to old myths, modern root canal therapy is the procedure that relieves that debilitating toothache. A skilled decay dentist or a specialist endodontist carefully and gently cleans the infected pulp from within the tooth’s canals. The area is then disinfected and sealed to prevent reinfection. It is a precise, caring procedure with one ultimate goal: to end your pain and save your natural tooth.
No matter the extent of the decay, there is a path back to a healthy, pain-free smile. For complex cases or severe pain, seeking specialised care is key. A consultation with an expert in saving teeth, like the team at Root Canal London, ensures you receive the most compassionate and precise treatment available.
When Deep Decay Requires a Specialist Endodontist
Your general dentist is your primary partner in the fight against tooth decay, expertly handling fillings and routine care. However, when decay penetrates deep into the tooth and infects the inner pulp, a specialist’s touch is often required to save it. For these complex cases, a general decay dentist will refer you to an endodontist, ensuring you receive the most advanced and focused care available.
What is an Endodontist?
An endodontist is a highly trained dentist who has completed several years of additional, specialised education in diagnosing and treating problems inside the tooth. They are experts in root canal therapy and other procedures aimed at saving teeth. With a deep understanding of tooth pain and its causes, their entire practice is dedicated to relieving discomfort and preserving your natural smile with skilled, compassionate care.
Signs Your Tooth Needs Specialist Attention
While your dentist can manage early decay, certain symptoms suggest the problem has reached a critical stage that benefits from specialist intervention. It’s time to see an endodontist if you experience:
- Severe, spontaneous, or throbbing tooth pain that disrupts your sleep.
- A dental abscess, which appears as a pimple-like swelling on the gum.
- Extreme and lingering sensitivity to hot or cold temperatures.
- Discomfort when chewing or touching the tooth.
- A tooth that requires retreatment after a previous root canal has failed.
The Specialist Advantage: Precision, Technology, and Comfort
Choosing an endodontist means choosing a higher level of precision. We use state-of-the-art tools like surgical operating microscopes to navigate and clean the intricate canals inside your tooth-a level of detail that dramatically increases the procedure’s success rate. This focus, combined with advanced pain management techniques and a calm, reassuring environment, ensures your experience is as comfortable and stress-free as possible. When your tooth’s future is on the line, specialist expertise makes all the difference.

Frequently Asked Questions About Tooth Decay
Is getting a cavity filled by a dentist painful?
Your comfort is our highest priority, and we strive to make every treatment a calm and pain-free experience. Before filling a cavity, your dentist will use a local anaesthetic to completely numb the tooth and surrounding area. You may feel some slight pressure during the procedure, but you should not feel any pain. Our caring team is here to ensure you feel at ease from start to finish, providing gentle and reassuring care throughout your appointment.
Can you stop or reverse tooth decay once it starts?
In its very earliest stage, known as demineralisation, tooth decay can be stopped and even reversed with improved oral hygiene and fluoride treatments. However, once the decay has broken through the enamel and created a physical hole, or cavity, it cannot be reversed. At this point, the damaged tooth structure must be removed by a dentist and restored with a filling to prevent the decay from progressing further into the tooth and causing more significant problems.
What happens if you leave tooth decay untreated for too long?
Ignoring tooth decay allows it to spread deeper into the tooth, leading to more severe consequences. The cavity can reach the sensitive inner pulp, causing intense toothache and infection, which may result in an abscess. If left untreated, the infection can spread to the jawbone and surrounding tissues. Ultimately, the tooth structure may become so compromised that the only remaining options are a complex root canal treatment or complete extraction of the tooth.
How can I prevent tooth decay from happening in the first place?
Prevention is the most effective strategy. A consistent daily routine of brushing your teeth twice a day with fluoride toothpaste and flossing once a day is crucial. It is also important to limit your intake of sugary and acidic foods and drinks, especially between meals. Most importantly, attending regular check-ups and hygiene appointments allows your dentist to spot and address any early signs of decay before they become a serious issue, keeping your smile healthy and strong.
How does a dentist know if I need a filling or a root canal?
The decision depends entirely on how far the decay has advanced into your tooth. A skilled decay dentist will use a clinical examination and digital X-rays to assess the depth. If the decay is confined to the outer layers (enamel and dentin), a filling is sufficient to restore the tooth. However, if the decay has reached the tooth’s inner pulp chamber, infecting the nerve, then a root canal is necessary to save the tooth from extraction and relieve the pain.
Is it better to extract a badly decayed tooth or save it?
Our professional philosophy is to save your natural tooth whenever it is possible and practical to do so. Saving a tooth with treatments like a root canal and crown maintains your natural bite, prevents neighbouring teeth from shifting, and preserves your jawbone. While extraction may seem like a simpler option, it often leads to more complex and costly restorative treatments in the future, such as bridges or dental implants, to fill the resulting gap.
