According to the IDA, various chemical and physical agents can be used to whiten teeth. Off-the-shelf products typically rely on a carbamide peroxide solution varying in concentration from 10% to 22%. But what makes professional whitening cost a bit more is the difference in the active ingredients found in the whitening agent.
Professional teeth whitening procedures have:
- Dental Supervision - Before the whitening procedure, your dentist will perform a dental examination to ensure that your gums and teeth are healthy for the treatment and determine if there are any crowns or veneers that will not be whitened.
- Stronger Whitening Agents - Professional in-office whitening procedures are carefully monitored and contain a higher concentration of whitening gel. For some patients, this may cause temporary sensitivity, and the dentist may place a gel on the gum tissue, so the soft tissues of the mouth are not irritated by the whitening gel.
- Faster Results - Nevertheless, because the concentration of professionally applied whitening gel is stronger than what you'd get in an at-home whitening product, results are visible immediately rather than several weeks afterward.
It is essential to know that teeth discoloration may be caused by a specific underlying disease or condition that requires dental therapy. So, visit your dentist for a consultation before choosing a method to brighten your smile.
