Thinking of Skipping X-Rays Before Getting Invisible Braces? Think Again | Zenyum SG

Many DIY invisible braces skip the X-rays before treatment. And a few brands insist on them. So why are X-rays important when it comes to straightening your teeth? Find out here.

Here’s something to think about.  

In a world where you can have almost anything delivered to your door within 24 hours of clicking ‘Check Out,’ why should you have to jump through multiple hoops just to get your teeth straightened? 

Especially since you opted for invisible braces, where the treatment time is significantly shortened compared to traditional braces?

 And more specifically:

  • Why do some invisible braces providers insist on you getting X-rays done before your orthodontic treatment?
  • Why are they so important?
  • Can’t you just opt for a DIY braces provider where X-rays are non-mandatory?


TLDR: YES – X-rays are incredibly important when it comes to orthodontic treatments.

What are X-rays?

X-rays, also known as radiographs, are images created when a beam of radiation called electromagnetic waves passes through the body and hits a sensor on the other side.

This process creates pictures that reveal the differences in the densities of the tissues through which they pass. And in the specific case of dental X-rays, here’s what you’ll see at the dentist’s office:

  • Enamel and fillings – Because these are dense, they’ll appear white in colour on the radiograph
  • The bone around the teeth, root canals, and decay – Because these are less dense, these, therefore, appear darker in colour on the radiograph 

 That said, there are several types of dental X-rays, which record slightly different views of your mouth. Common examples include:

  • Bitewing: This is where you bite down on a special piece of paper so your dentist can see how well the crowns of your teeth match up. Typically used to check for cavities between teeth.
  • Occlusal: Done when your jaw is closed to see how your upper and bottom teeth line up. This can also be used to detect anatomical abnormalities with the floor of the mouth or palate.
  • Panoramic: This is where the X-ray machine rotates around the head.  Helps to check wisdom teeth, plan for implanted dental services, or investigate jaw problems.


Are orthodontic X-rays safe?

If your eyes boggled at the word ‘radiation’ and your mind immediately went to the scariest word of all, ‘Cancer’… 


Orthodontic X-rays are absolutely safe.

The amount of radiation you’d get from an orthodontic X-ray is 0.010 millisieverts, which is only a little more than the radiation you receive just walking around outside in the sun during a normal day.

And because this is Singapore, where we’re this close (1-degree, to be specific) from the equator, you might have exposed yourself to more radiation during your Outward Bound Singapore (OBS) days back in secondary school than when taking orthodontic X-rays.

Besides, most orthodontists use a lead apron that protects the chest and the neck during these X-rays to limit your radiation exposure. 

There’s really no need to worry.

Why are X-Rays so important?

1. Identify pathology

Because of their nature, X-rays can determine if your oral health is great, or not.

Just so you know, many dental conditions such as periodontal disease–which affects 20 to 50% of the population–are slow-progressing, often asymptomatic, and remain undetected until later stages.

And scarily enough, orthodontic tooth movement (no matter from traditional or invisible braces) in patients with active periodontal disease has been shown to aggravate the condition, potentially leading to tooth loss.

Dentists/orthodontists don’t only check for any pre-existing periodontal disease through X-rays, too.

 Instead, they have to keep an eye out for any type of dental abnormalities, including impacted teeth, cysts, and supernumeraries. That’s because whenever present in a patient, these issues need to be resolved before orthodontic treatment can proceed – if at all.


ALWAYS check for and resolve any dental issue BEFORE proceeding with invisible braces.

2. X-Rays help orthodontists map a teeth-straightening plan unique to your needs

Here’s something fun to try: go take a look at your family members’ teeth. Chances are, their teeth (i.e. shape, length, width) are going to look different from yours.

 The point being, your orthodontist may have to take your unique needs into account when designing a teeth-straightening treatment for you. For example, you may have problems with the jaws where your bones are:

  • Too big
  • Too small
  • Asymmetrical
  • Too far apart
  • Too close together
  • Misshaped

This is where X-rays come in. They provide orthodontists with the necessary information that not only help them determine where problems exist but also guide them on the best way to correct these issues (e.g. if extraction or surgery is required before treatment).

Don't skip it!

Ultimately, it’s essential to remember that orthodontic teeth movement without any in-person consultation or supervision of a qualified dentist, can lead to unsuccessful treatment outcomes, root resorption, tooth motility, and tooth loss.

That’s definitely not what you asked for when you wanted to straighten your teeth!

Not to mention, losing your teeth seems like a hefty price to pay in exchange for some convenience and instant gratification.
