Dental Onlay and Inlay vs Crown

Sometimes, fillings fall out. This can be from normal wear and tear, worsening decay of the tooth, or disease or infection. In this instance, either a dental onlay or inlay or a crown is used. This article will go over both dental options, as well as the advantages and disadvantages of each.

What Is It?

Dental Inlay and Onlay

Dental inlays and onlays are very similar techniques used to fill a hole in the tooth from cavity, injury, or decay. A dental inlay is crafted using the specifications of the hole in the tooth, as well as the tooth itself. A custom inlay is created to fill the hole and cover the tooth. An onlay is similar to this, however, it uses the cusps of the infected tooth to secure the onlay in place.


A crown is a fitting that covers the entire tooth. It is often used only when at least 50% of the tooth is infect. Dental inlays and onlays may not work in this situation.

Inlay/Onlay vs. a Crown

An inlay/onlay uses less material, so it is less expensive to fill than a crown. It also saves a lot more of the healthy tooth, preserving it to prevent further damage. The downside is that inlays and onlays will not work for all situations, especially if there is a moderate to severe amount of tooth decay. They also take two visits to be fitted instead of one, since they must be created for a customized fit.

The Benefits

Benefits of Inlays

  • Natural appearance
  • More durable than metal fillings
  • Will not wear and tear with exposure to hot and cold food
  • Resists force when you bite down
  • Care for them like you would your natural teeth
  • Customized for a better fit

Benefits of Onlays

  • Easy to clean
  • Helps preserve the natural tooth underneath
  • Will not shrink
  • Unlike to become discolored
  • Strong and stable

So, Which is Better?

Looking at the facts about each, it seems inlays and onlays are the better choice. They are customized for a better fit and withstand wear and tear. Additionally, they are easy to care for and help preserve the tooth. However, they will not work in all situations. Speak to your dentist about whether a crown or an inlay or onlay, or simply go with low cost of cfast braces whichever is best for your situation.

A Little More About Inlays and Outlays

You can expect to pay around $250-$1,500 for an inlay or $350-$1,500 for an onlay. The total cost will factor in several things, including the type of material used, how much material is worked on, and the dental office you choose to work with.

Usually inlays and onlays are fitted in two visits. During the first, a mold will be taken and during the second, it will be fitted to your tooth.

While it would seem inlays and onlays are the better choice, they will not work for extreme tooth decay or situations where 50% of the tooth is infected. Your dentist can offer more information and a recommendation based on your specific dental situation.

Electromagnetic Radiation

Electromagnetic radiation is a little-understood property of the physical universe. Despite the fact that we still know relatively little about this force, we have harnessed it in many different ways to help create the modern world in which we live.

The most familiar form of electromagnetic radiation that we all experience on a daily basis is what we call visible light. It is a strong argument in favour of the idea that there may be some truth in The Bible that the first created thing in the universe is light. Light is electromagnetic radiation of a certain bandwidth of frequencies – the spectrum of the rainbow shows us these different frequencies, from red to violet. You may also have heard of infra-red and ultra-violet, which are the first invisible frequencies you encounter on either side of the visible spectrum.

If you have a special camera, you can see infra-red, which we commonly refer to as heat. Anybody that is warmer than its surrounding environment will give off infra-red radiation. This would show up on an infra-red camera. It is strange to think that all of us are giving off a kind of light – we glow. If you have seen the film “Predator” you will be familiar with how people appear to an Infra-red sensitive camera.

Ultra-violet light, on the other hand, is only given off by certain electro-chemical reactions. The sun is a major source of ultra-violet light, in fact, it is the major source of electromagnetic radiation for the entire solar system. Most people cannot perceive any ultra-violet light at all, but certain small birds and insects do perceive ultra-violet light. Many butterflies, in fact, have patterns that are distinctly more extravagant when the ultra-violet component is taken into account. The same applies to many flowers.

Even with this wide variety of effects of electromagnetic radiation, from heat to ultra-violet, we have barely scratched the surface of what is contained within the electromagnetic spectrum. There are wavelengths that are much shorter, known as gamma rays, and those that are much, much longer, and these are referred to as radio waves. Of course, we have put both of these things to some use – microwaves are used in cooking and we all listen to the radio from time to time.

As I said, we have put the electromagnetic radiation in the Universe to a wide variety of uses – even painting your walls could be said to be a manipulation of the electromagnetic properties of your surroundings. Electromagnetic radiation is fundamental to the working of the entire universe, in some ways it is the entire universe. In Einstein’s famous equation E equals MC squared, on which much of our current model of the universe is built, E stands for the speed of light.
As I mentioned, light is given a great deal of weight by most religions as well, and this is perhaps one thing that the modern physical sciences agree on – light is extremely important! I particularly like Himalayan Salt Lamps for lighting my house, and in fact I just got my fourth one from Himalayan Salt Lamp Boutique. (You can keep up with Himalayan Salt Lamp Boutique updates on Facebook here.)

Quite funny considering light is weightless and may not be comprised of anything material at all. It’s nice to know that there are still many things we do not know. There may well still be a glittering and prosperous future ahead of all of us when the next outrageously useful property of light is discovered and harnessed.

Who knows?

I think everyone can agree that if we could remove the need to bill everyone for gas and electricity we would be moving in the right direction and that would be as great a leap as the invention of the light bulb.
