Teeth whitening can be effective at removing both surface stains and some deep stains, but its effectiveness depends on the cause of the discoloration. Surface stains caused by foods, drinks, and tobacco are more easily lifted by the bleaching agents used in whitening treatments. Deep stains, however, may result from factors such as aging, certain medications (like tetracycline), trauma to the teeth, or excessive fluoride exposure during tooth development. While professional teeth whitening can help lighten these deep stains, it may not completely remove them.

For more stubborn stains that do not respond well to standard teeth whitening, your dentist may recommend alternative treatments such as veneers or dental bonding to achieve the desired brightness. In-office whitening treatments that use stronger bleaching agents or light-activated technologies can sometimes achieve better results for deep stains compared to at-home whitening kits. It's best to consult with your dentist to determine the severity of the stains and the most effective treatment plan.

The recovery time after getting a dental crown is typically short, with most patients resuming their normal activities immediately after the procedure. However, it is common to experience some mild sensitivity or discomfort in the treated tooth for a few days. This sensitivity is often caused by irritation to the surrounding gums or nerves, especially if the tooth was significantly reshaped or if a temporary crown was worn for an extended period. Over-the-counter pain relievers and avoiding very hot, cold, or hard foods can help alleviate any discomfort.

For the first few days, patients are advised to chew carefully, particularly if the crown was placed on a molar or premolar. It's also important to maintain good oral hygiene, including brushing and flossing around the crown, to prevent plaque buildup and protect the underlying tooth. In cases where the crown is fitted after a root canal, recovery may take slightly longer, and any lingering sensitivity should be monitored by a dentist. Most patients feel fully adjusted to their new crown within a week, and the crown can function just like a natural tooth for many years with proper care.
