A woman has pleaded guilty to carrying out unlawful tooth whitening at a Lancaster salon.
Natalie Kowalczyk was prosecuted by UK regulator the General Dental Council (GDC) because she was not a registered dental practitioner.
The offence took place at Jo & Cass hair salon on Great John Street.
Kowalczyk admitted unlawfully practising dentistry during a hearing at Lancaster Magistrates Court.
She was sentenced to a 12 month conditional discharge and ordered to pay a £15 victim surcharge.
Kowalczyk was also ordered to pay £250 compensation to the victim for pain and suffering and £65 compensation to the victim for reimbursement of the cost of the treatment.
She has also been ordered to pay costs to the GDC of £1468.63.
By law, tooth whitening must only be carried out by registered dentists, dental hygienists, dental therapists and clinical dental technicians (working to the prescription of a dentist).
