Almost everyone wants a perfectly aligned smile, but the decision to begin orthodontic treatment often comes with a major dilemma: „Which type of device is best for me?”While metal braces used to be the only option available, today's technology offers modern, much more discreet alternatives.".
At Dr. Nicolau’s Dental Clinic, patients frequently ask us what the real differences are between invisible braces (clear aligners) and traditional metal braces. To help you make the best decision, we’ve analyzed the pros, cons, and selection criteria for both options in this article.
What are metal braces, and when are they recommended?
Fixed braces with metal brackets are the most commonly used method in orthodontics. They work by bonding brackets to the surface of the teeth; these brackets are connected by a metal wire that is periodically adjusted by the orthodontist.
Advantages of the metal appliance:
- Efficiency in Complex Cases: It can correct severe bite abnormalities (malocclusions) and complex tooth rotations that other systems cannot address as easily.
- Ongoing treatment: Since it is a stationary device, it operates continuously (24/7), and the success of the treatment does not depend on the patient's discipline.
- Excellent value for the price: In most cases, metal braces are the most affordable option.
Disadvantages:
- Aesthetics: It is the most noticeable type of braces.
- Difficult to sanitize: It requires extra care when brushing and the use of special interdental brushes to remove food particles from around the braces.
What are invisible braces (clear aligners)?
Invisible braces use a set of clear, medical-grade plastic aligners, custom-made in a laboratory based on a 3D digital scan of the teeth. These aligners apply controlled, gradual pressure to move the teeth into the correct position.
The advantages of invisible braces:
- Premium aesthetics: The aligners are almost completely invisible, making them ideal for adults who want to maintain their confidence in social and professional settings.
- Superior comfort and hygiene: The appliance is removable. You take it out during meals, which means you have no dietary restrictions, and you can brush and floss your teeth just as you normally would.
- Fewer visits to the clinic: Setup does not require complex manual adjustments, and follow-up visits can be less frequent compared to a conventional device.
Disadvantages:
- It requires discipline: To be effective, the device must be worn for at least 22 hours a day. If you forget to put it back on after a meal, the treatment will take longer.
- Technical limitations: It is not recommended for extremely severe orthodontic cases, where the traction force of a fixed appliance is required.
Traditional vs. Invisible Braces: A Direct Comparison Guide
To choose the right option between the two, it's helpful to compare them based on your lifestyle:
| Selection criterion | Classic metal appliance | Invisible Braces (Aligners) |
| Visibility | Braces (metal braces) | Very thin (clear plastic) |
| Device Type | Fixed (does not go home) | Portable (used for meals and personal hygiene) |
| Dietary Restrictions | Yes (no hard or sticky foods) | No (remove it during the meal) |
| Wear time | Permanent | At least 22 hours a day |
| Case Complexity | Any type of anomaly | Mild, moderate, and moderately complex cases |
How do you choose the right braces for you?
The final decision isn't just about aesthetics or the price of the braces. The most important factor is the diagnosis made by the orthodontist based on the results of the examinations (X-rays, CT scans, and intraoral scans).
If you have an active lifestyle, work closely with people, and want total flexibility, clear aligners are probably your best option. However, if your case is complex or you prefer a treatment you can „wear” (without having to worry about taking the aligners out and putting them back in), traditional braces remain a reliable solution.
At Dr. Nicolau Dental Clinic, we use state-of-the-art digital technology to show you a simulation of the final result even before treatment begins. That way, you’ll know exactly what your smile will look like at the end of your journey.

Frequently Asked Questions
In many mild or moderate cases, yes, treatment with clear aligners can be faster. This is due to 3D digital planning technology, which calculates the movement of each tooth with millimeter precision. However, the total duration depends entirely on the complexity of your case and how strictly you wear the aligners (at least 22 hours a day).
No matter which option you choose, you’ll feel a slight pressure or discomfort in the first few days after getting metal braces or after switching to a new set of clear aligners. The difference is that invisible aligners apply more consistent and gentler forces, completely eliminating the risk of wires or brackets scratching your cheeks or lips.
If you choose traditional metal braces, you’ll need to see your orthodontist once every 4–6 weeks to have the wires adjusted and replaced. With clear aligners, you’ll receive several sets of aligners that you change yourself at home every 1–2 weeks, which means visits to the clinic can be less frequent—usually every 6–8 weeks.
Yes, and that’s one of the biggest advantages. Since you remove the aligners while eating, there are no dietary restrictions. You can still eat hard foods (nuts, apples) or sticky foods, which could cause the brackets to come loose if you were wearing metal braces. The only rule is to brush your teeth before putting the aligners back in.
In general, traditional metal braces have a lower initial cost and are the most economical option. Invisible braces require a greater financial investment, which is justified by the customized digital technology, the premium materials used, and the complete aesthetic comfort they provide throughout treatment.
