Homonym: retainer (Dental)
A "retainer" is a type of legal agreement where a client pays a lawyer or law firm a set fee to secure their services for a specific period. This arrangement ensures that the lawyer is available to provide legal advice and representation as needed, without the client having to pay for each individual service separately.
In addition to legal contexts, the term "retainer" can also refer to a dental device used to maintain the position of teeth after orthodontic treatment, such as braces. This helps prevent teeth from shifting back to their original positions, ensuring the results of the treatment are preserved.
