According to dentists at Smilux, teeth may not become white after whitening due to thin enamel, deep staining, dental crowns, old fillings, or an unsuitable whitening technique.
The growth of social media, along with the increasing demand for smile care, has made many teenagers and adults more interested in teeth whitening methods. However, to whiten teeth safely and achieve good results, the appropriate age for the procedure should be carefully considered based on the condition of the teeth, tooth enamel, and oral health.
So, At What Age Can You Whiten Your Teeth? When can teeth whitening be performed safely, and what is the best time to achieve optimal results? Let’s find out in detail with the dentist at Smilux Dental in the article below.
At What Age Can You Whiten Your Teeth? According to the dentists at Smilux Dental, teeth whitening should only be performed from the age of 18 and above.
This is when the permanent teeth have developed stably, the tooth enamel is stronger, and the pulp chamber is no longer as sensitive as it is during the teenage years. As a result, the teeth whitening process is safer and helps reduce the risk of prolonged tooth sensitivity or pulp irritation.
Before the procedure, the dentist will conduct a thorough examination to assess the condition of the enamel, gums, and level of tooth discoloration, then choose the most suitable whitening method.
| Age Group | Teeth Whitening Recommendation |
| Under 13 years old | Teeth whitening is not recommended. At this age, the permanent teeth and tooth enamel have not yet developed stably, and the pulp chamber is still large, making the teeth more prone to sensitivity, irritation, or discomfort after using whitening agents. |
| 14–16 years old | Teeth whitening should only be performed when indicated and monitored by a dentist. If the teeth are discolored, the dentist may prioritize gentler methods such as plaque removal, tooth polishing, or suitable dental care products instead of intensive whitening. |
| 17–19 years old | Teeth whitening may be considered after a dental examination. For patients aged 18 and above, the permanent teeth are usually more stable, and the enamel is stronger, making them more suitable for professional whitening methods, especially in cases of tooth discoloration after braces. |
| 20 years old and above | This is a more suitable age for professional teeth whitening. At this stage, the tooth structure has developed stably, and the dentist may choose in-office whitening or at-home whitening with custom trays. |
Besides wondering At What Age Can You Whiten Your Teeth?, many patients are also concerned about whether teeth whitening has a maximum age limit. According to the dentists at Smilux Dental, there is no maximum age limit for teeth whitening. You can still have it done at the age of 40, 50, or older, as long as your teeth and gums are healthy.
The American Academy of Pediatric Dentistry (AAPD) does not recommend that parents whiten their children’s primary teeth. For children, teeth whitening should only be considered once all permanent teeth have fully erupted and must be directly examined and prescribed by a dentist. In addition, parents should not let children use at-home teeth whitening kits or whitening products purchased online without guidance from a dentist.
This is because primary teeth have thinner enamel and dentin than permanent teeth, while the pulp chamber is larger. When exposed to whitening agents, children’s teeth are more likely to become sensitive, sore, or painful compared with adults’ teeth. In addition, primary teeth will be replaced as part of the natural tooth eruption process, so the whitening results will not last long.
If a child’s teeth are severely discolored, parents should take the child to a pediatric dentist to check the underlying cause. Depending on the specific condition, the dentist may recommend a more suitable aesthetic option, such as composite dental bonding, instead of whitening primary teeth when it is not necessary.
