Why Do Dentists Push for Crowns?

Why do dentists push for crowns? Dentists recommend crowns because they want to save your natural tooth from breaking or falling out. A crown acts like a helmet for your tooth. It covers the entire top part of the tooth down to the gum line. This makes the tooth strong again. If your dentist says you need a crown, they are trying to prevent a bigger problem like a tooth infection or a tooth that snaps in half. You should listen to this advice because saving a tooth is much cheaper than replacing a tooth later.

Is a Crown Better Than a Large Filling?

Yes, a crown is much better than a large filling when a tooth has a lot of decay. Fillings work well for small holes, but they do not work well when more than half of the tooth is gone. Research shows that large fillings actually make a tooth weaker. When you bite down on a large filling, the filling acts like a wedge and it pushes against the walls of your tooth. This pressure causes the tooth to crack or split open over time. A crown does the opposite because it wraps around the tooth and holds it together. Data from dental studies shows that teeth with crowns are 75 percent less likely to break than teeth with very large fillings.

You should choose a crown if your filling is wider than half the width of your tooth. Dentists see this every day. They see patients come in with a broken tooth because they tried to get another filling instead of a crown. When a tooth splits deep under the gum, no one can fix it and the dentist must pull it out. A crown prevents this from happening. It keeps the pressure off the weak parts of your tooth and lets you chew food without fear.

Will a Crown Protect My Tooth After a Root Canal?

Yes, a crown is mandatory after almost every root canal on a back tooth. When a dentist performs a root canal, they remove the blood vessels and nerves from inside the tooth. This process makes the tooth very brittle and dry. A dry tooth is like a dry twig because it breaks easily. Statistics show that back teeth with root canals that do not get a crown will fail within five years in most cases. A crown seals the tooth and stops bacteria from getting back inside the roots. It also provides the strength needed to grind up food. You must protect your investment in the root canal by placing a crown on top of it immediately.

How Much Do Dental Crowns Cost in Australia?

A dental crown in Australia usually costs between 1500 dollars and 2500 dollars for one tooth. This price depends on the material the dentist uses and how difficult the tooth is to reach. While this seems like a lot of money, it is a smart investment. Evidence shows that a crown lasts between 10 and 15 years on average. Some crowns even last 20 years if you brush and floss them well. If you divide 2000 dollars by 10 years, the cost is only 200 dollars per year to keep your tooth. This is much cheaper than a dental implant, which can cost over 5000 dollars in Australia. Many private health insurance plans in Australia pay for part of the crown cost. This can lower your out of pocket price to 1000 dollars or less.

What Happens if I Refuse a Crown?

If you refuse a crown, your tooth will eventually break. This is not a guess, it is a fact. When a tooth has a large crack or a huge filling, the daily stress of chewing will finish it off. You might be eating something soft like bread and suddenly hear a loud pop. That is the sound of your tooth splitting. If the crack goes deep into the root, the dentist cannot save the tooth. You will then have a gap in your smile. This gap causes your other teeth to shift and move. Shifting teeth lead to jaw pain and more decay. Saying no to a crown today often means paying for an extraction and an implant tomorrow. An implant is a great tool, but it is always better to keep your real tooth if you can.

Are There Different Types of Crowns I Can Choose?

Yes, there are four main types of crowns and each one has a specific job. Your dentist will choose the best one based on where the tooth is in your mouth and how hard you bite.

1. Zirconia Crowns. These are the strongest crowns available today. They are made of a type of metal crystal that is white. They are very hard to break. They are perfect for back teeth where you do the most chewing.
2. Porcelain Crowns. These look the most like real teeth. Dentists use these for front teeth because they reflect light just like natural enamel. They are beautiful but can chip easier than zirconia.
3. Gold Crowns. Gold is the best material for the health of your mouth. It does not wear down the teeth it bites against. It is very thin so the dentist does not have to remove as much of your natural tooth. Most people only use gold on the very back molars.
4. Porcelain Fused to Metal. These have a metal inside for strength and porcelain on the outside for looks. They have been used for decades and work very well, but sometimes a dark line shows near the gum.

How Long Does It Take to Get a Crown?

Getting a crown usually takes two separate visits to the dentist. During the first visit, the dentist numbs your tooth and shapes it. They remove the decay and old fillings. They make the tooth smaller so the crown can fit over it like a cap. The dentist then takes a mold or a digital scan of your mouth. They send this to a dental lab. You will wear a temporary plastic crown for about two weeks while the lab makes your permanent one. During the second visit, the dentist removes the temporary crown and glues the permanent one in place. Some modern offices use a machine called CEREC to make the crown in one day. This uses a computer to mill the tooth out of a block of ceramic while you wait. Both ways result in a strong tooth that functions just like the original one.

Do Crowns Feel Like Real Teeth?

Yes, after a few days, you will not even notice the crown is there. Modern dental materials feel smooth to your tongue. Dentists check your bite very carefully to make sure the crown hits the opposite tooth at the right time. If the crown feels too high, the dentist can polish it down in seconds. Evidence shows that patients with crowns can eat all the foods they love, including steak and apples, without any pain. You should still avoid chewing on ice or hard candy because even a crown can break if you abuse it. If you treat your crown like a natural tooth, it will serve you for many years.

Why Do Dentists See Problems I Can Not Feel?

Dentists use tools that see things you cannot feel yet. Many people ask why they need a crown when the tooth does not hurt. The truth is that if you wait for it to hurt, it is often too late. Pain usually means the nerve is dying or the tooth has a deep infection. Dentists use high powered lights, mirrors, and X rays to find small cracks. These cracks are like a tiny chip in a car windshield. If you do not fix the chip, it will spread across the whole glass. Data shows that fixing a tooth before it hurts has a much higher success rate. A crown placed on a healthy tooth is much more stable than a crown placed on a tooth that has already started to rot or break.

How Can I Make My Crown Last 20 Years?

You make a crown last by keeping the base of the tooth clean. A crown cannot get a cavity, but the natural tooth underneath it can. If bacteria get under the edge of the crown, the tooth will rot. You must brush twice a day and floss every single night. You should use a fluoride toothpaste to keep the tooth roots strong. Also, you must visit your dentist every six months for a professional cleaning. The hygienist uses special tools to clean around the edges of the crown where your toothbrush cannot reach. Studies show that people who get regular cleanings keep their crowns twice as long as people who stay away from the dentist.

Common Questions About Dental Crowns

Does getting a crown hurt?

No, the process does not hurt. The dentist uses a local anesthetic to numb the area completely. You will feel some pressure while they work, but you will not feel pain. After the numbing wears off, your gums might feel a little sore for a day or two. You can take simple pain relief from the chemist to help with this.

Can a crown fall off?

It is rare, but it can happen. This usually happens if the glue gets old or if you eat something very sticky like a hard toffee. If your crown falls off, do not panic. Keep the crown and call your dentist immediately. They can often clean it and glue it back on. Do not try to glue it back yourself with superglue because you will ruin the tooth and the crown.

Is there an alternative to a crown?

The only real alternative to a crown for a badly damaged tooth is an onlay. An onlay is like a partial crown. It covers only the chewing surface. However, if the tooth is very weak, an onlay will not provide enough protection. If the tooth is too far gone for an onlay or a crown, the only choice left is to pull the tooth out and get an implant. In these cases, the only choice left is an extraction and implant.

Why does my crown look dark at the gum line?

This usually happens with older porcelain fused to metal crowns. The metal inside the crown shows through as a dark shadow. Modern zirconia or all porcelain crowns do not have this problem. If you are worried about how your crown looks, tell your dentist you want a metal free option.

The Final Answer on Crowns

Dentists push for crowns because they are the gold standard for saving teeth. They provide a predictable result and high levels of strength. Choosing a crown when your dentist suggests it is the best way to avoid emergency surgery and high costs in the future. It is a protective move that keeps your smile whole and your mouth healthy. If you have a large filling that is more than five years old, you should ask your dentist if a crown is needed to protect it from splitting. Taking action now is the best way to ensure you can keep chewing and smiling for the rest of your life.
