Cavity vs Filling Cost: Why Ignoring a Small Hole Becomes Expensive

That Small Dark Spot You’ve Been Ignoring

I see it all the time. A patient sits down, and during the examination, I spot a cavity they’ve been aware of for months, sometimes longer. "I know it’s there," they’ll say, "but it doesn’t hurt yet, so I thought I’d wait." Or: "How much is a filling? Maybe I’ll just leave it."

I understand the hesitation. Dental work feels expensive when you’re looking at the immediate cost. But what I’ve learned over nearly two decades of practice is that the real expense isn’t the filling, it’s what happens when you don’t get one.

Today, I want to walk you through exactly what a cavity costs to fix now, versus what it will cost to fix later. And I’ll be honest about the numbers, because that’s how we work here at Pune Dental Studio.

How a Cavity Actually Grows

Let me explain what’s happening inside that tooth right now, while you’re reading this.

A cavity isn’t just a hole. It’s an active bacterial infection eating through the layers of your tooth. It starts in the enamel, the hard, protective outer shell. At this stage, it’s small, painless, and relatively easy to stop.

But bacteria don’t stop working. They keep spreading inward, deeper into the softer layer beneath called the dentin. This is where things change. The dentin is more porous, so decay spreads faster here. Your tooth might start to feel sensitive to cold or sweet things. You’re still okay, but the window is closing.

If you wait longer, the decay reaches the pulp, the nerve chamber inside your tooth. Now you have pain. Real pain. And now you need a root canal, not just a filling.

Wait even longer, and the infection can spread beyond the tooth into your jaw and bloodstream. I’ve had patients arrive at my clinic in genuine distress because they ignored a cavity for years.

The Cost of a Composite Filling (Right Now)

Let’s be specific. At Pune Dental Studio, a tooth-coloured composite filling, which is what I recommend for most cavities, typically costs between ₹2,000 and ₹6,000, depending on the size and location of the cavity.

A small cavity on the front surface of a tooth? Closer to ₹2,000–₹3,000.

A larger cavity between two teeth, or on a back molar? Closer to ₹4,000–₹6,000.

The procedure takes 30 to 45 minutes. I clean out the decayed part, prepare the tooth, and fill it with composite resin, a tooth-coloured material that bonds directly to your tooth. It’s durable, looks natural, and if you care for it properly, it lasts many years.

That’s it. You walk out, and the problem is solved.

What Happens If You Don’t Treat It

Now let’s look at the path you’re on if you ignore it.

Stage 2: The Root Canal

Six months to two years later, the decay reaches your nerve. You’re in pain, maybe sharp, maybe a dull throb that keeps you awake at night. You finally call the dentist.

Now you need a root canal treatment (RCT). This is a procedure where I remove the infected nerve tissue from inside your tooth, clean the canal, and seal it. It’s more complex than a filling, takes longer, and costs significantly more.

At our clinic, a single-sitting root canal typically costs between ₹8,000 and ₹15,000, depending on which tooth and how complicated the infection is.

That’s already 3 to 5 times the cost of the filling you could have had.

But wait, there’s more.

Stage 3: The Crown

Here’s something many people don’t realize: a tooth that’s had a root canal becomes brittle. The nerve is gone, so the tooth no longer gets blood supply. It becomes dry and prone to cracking.

To protect it, you need a crown, a custom cap that covers the entire tooth.

A dental crown at Pune Dental Studio ranges from ₹7,000 to ₹25,000 depending on the material you choose. A basic metal crown is on the lower end; a premium zirconia crown (which looks completely natural) is on the higher end.

So now you’re looking at: filling cost (₹2,000–₹6,000) + root canal (₹8,000–₹15,000) + crown (₹7,000–₹25,000) = ₹17,000 to ₹46,000.

That’s 3 to 10 times what you would have paid for a simple filling.

Stage 4: Extraction and Replacement

If you wait even longer, or if the infection is severe, the tooth might become unsalvageable. Now you need an extraction.

A simple extraction costs ₹1,500–₹5,000. But you’ve now lost a tooth.

To replace it, you have two main options:

Option A: A dental implant. This is a titanium post surgically placed into your jawbone, topped with a crown. Cost: ₹30,000–₹60,000+, depending on complexity and the crown material.

Option B: A dental bridge. This uses the teeth on either side to anchor a false tooth. Cost: ₹15,000–₹54,000 depending on the span and materials.

Either way, you’re now spending ₹15,000 to ₹60,000+ to replace a tooth that you could have saved for ₹2,000–₹6,000.

The Real Math

Let me lay this out clearly:

• Filling now: ₹2,000–₹6,000
• Filling + RCT + Crown (later): ₹17,000–₹46,000
• Extraction + Implant or Bridge (much later): ₹15,000–₹60,000+

The difference between catching it early and ignoring it can be ₹10,000 to ₹54,000.

That’s not just money. That’s also multiple appointments instead of one, more time away from work, more discomfort, and a tooth that’s never quite the same as your original.

Why People Still Wait

I know the reasons. Cost feels real when you’re looking at it today. Pain doesn’t feel real until it arrives. And there’s a strange human tendency to hope that if we ignore a problem, it’ll go away on its own.

It won’t. Cavities never heal themselves.

What I tell my patients is this: a filling is an investment in keeping your tooth. It’s the cheapest insurance you can buy.

What Happens During a Filling Appointment

I want to ease any anxiety about the procedure itself, because I know that’s often what keeps people away.

First, we do a consultation and digital scan. I use a 3D intraoral scanner, no gooey impression trays, so you can see exactly what’s happening in your mouth on a screen.

Then, I apply a strong topical numbing gel before any injection. This makes the freezing virtually unnoticeable. Many patients tell me they barely felt it.

Once the tooth is numb, I remove the decayed part using a small drill. You’ll hear the sound, but you won’t feel pain, just pressure and vibration.

I then clean the cavity thoroughly and apply a bonding agent. The composite filling is placed in layers and hardened with a special light. Finally, I shape and polish it so it matches your bite and looks natural.

The whole thing takes 30 to 45 minutes. You drive home, eat normally (though I suggest waiting an hour before eating hard foods), and you’re done.

Aftercare and How Long It Lasts

A composite filling, if cared for properly, lasts 5 to 10 years or longer. Sometimes much longer.

How do you care for it? The same way you care for your natural teeth:

• Brush twice a day with a fluoride toothpaste
• Floss daily
• Avoid chewing on hard objects (ice, hard candy, your pen)
• See me for a check-up every 6 months

That’s it. No special maintenance.

If you grind your teeth at night, a night guard helps protect the filling (and all your teeth). If you have other risk factors, like dry mouth or acidic diet, we can discuss additional preventive measures.

Why Composite Over Other Options?

At Pune Dental Studio, I recommend composite fillings for most cavities because they:

• Look natural. They’re tooth-coloured and blend seamlessly.
• Bond to your tooth. They don’t require removing as much healthy tooth structure as older amalgam (silver) fillings.
• Are versatile. They work on front teeth and back teeth.
• Are durable. Modern composites are strong enough for any location in your mouth.

Amalgam fillings are cheaper, but they require more tooth removal, they look silver, and many patients prefer to avoid them for cosmetic reasons.

The Transparency You Deserve

Here’s what I promise: when you come in with a cavity, I’ll tell you exactly what it will cost to fix it. Before any treatment, you’ll have a written treatment plan with pricing. No surprises at checkout. No pressure to do more than you need.

If you’re worried about cost, we can discuss it openly. Sometimes there are ways to prioritize treatment or explore payment options. But I won’t let financial anxiety push you toward ignoring a cavity, because that’s where the real expense lies.

A Final Word

I’ve been practicing dentistry since 2006. In that time, I’ve seen countless patients who delayed treatment because they were afraid of the cost, only to end up spending 10 times as much later.

I’ve also seen patients who caught cavities early, got a simple filling, and never thought about it again.

The choice is yours. But the math is clear.

If you’ve noticed a cavity, or if you’re not sure, the best thing you can do is come in for a consultation. I’ll take a digital scan, show you exactly what’s happening, and give you an honest assessment. No pressure. No judgment. Just clarity.

Because that small dark spot you’ve been ignoring? It’s not going to stay small. And the sooner we address it, the simpler, and cheaper, the solution.

Frequently Asked Questions

How long does a filling last?

A composite filling typically lasts 5 to 10 years or longer, depending on the size of the cavity, where it is in your mouth, and how well you care for your teeth. Back molars experience more chewing force, so fillings there may need replacement sooner than fillings on front teeth.

Will a filling hurt?

No. Once the tooth is numb (which happens with a topical gel first, so the injection is painless), you won’t feel pain during the filling. You’ll feel pressure and vibration, and you’ll hear the drill, but not pain.

Can I eat right after a filling?

I suggest waiting about an hour before eating, just to let the composite fully harden. Avoid hard, sticky, or very hot foods for the first 24 hours. After that, you can eat normally.

What if I have multiple cavities?

We can often treat multiple cavities in one or two appointments, depending on how many and where they are. I’ll discuss a treatment plan with you.

Is a composite filling as strong as an amalgam filling?

Yes. Modern composite materials are just as durable as amalgam for most situations. The advantage is that they look natural and require less removal of healthy tooth structure.

What if I’m very anxious about dental work?

We specialize in working with anxious patients. We use topical numbing before injections, noise-cancelling headphones, aromatherapy, and a calm environment. We also go at your pace, you can pause treatment at any time. Many of our most anxious patients find that the experience is far less scary than they expected.
