Everyone at Smiles Ahead has been so amazing. I had to go in as an emergency patient and they got a slot for me that morning. I had a panicky episode on my first visit but I was given the right support to get me ready for my next visit and tooth extraction. That first evening, I had a call just to check I was doing okay which was greatly appreciated. When I then went back for the extraction, everyone was so reassuring and patient with me, explaining each step and putting soothing music on. I sat in the waiting area afterwards while they kept an eye on me because I was very shaky, and they checked I would be okay getting home. Appointments have been on time, staff have all been friendly and very understanding of how anxious I have been. They couldn’t have done more to make me feel at ease. Highly recommend. I will always come back here now.

Dr. Khurram Quershi has been helping people improve their dental health for over 20 years. His caring nature means he’s committed to understanding his patients’ needs and making a real difference in their lives.
Dr. Quershi will patiently walk you through your treatment options, taking time to address your concerns and fully explain the process, guiding you from your initial consultation to your final Invisalign aligner. He’s helped hundreds of people in Corby and the surrounding areas of Weldon, Great Oakley, Northamptonshire, and beyond to get the smile they’ve always wanted.






Invisalign uses a series of clear, removable aligners that are custom-made to fit your teeth. Each set gently shifts your teeth little by little until they’re in their ideal position. You’ll typically wear each aligner for 1–2 weeks before moving on to the next one.
Most people find Invisalign much more comfortable than traditional braces. You may feel a bit of pressure or tightness when switching to a new set of aligners, but this usually fades after a day or two.
Your treatment time will depend on your needs, so it varies from person to person. Once you’ve had your consultation, your dentist can give you a personalised timeline, but it’s usually between 9 and 18 months.
You should remove your aligners before eating or drinking anything other than water. This helps avoid staining and keeps your aligners in great shape. That means no food restrictions during your treatment, so you can enjoy all your favourites without worry.
For the best results, you should wear your Invisalign aligners for 20–22 hours a day. That means keeping them in while you sleep and only taking them out to eat, drink, brush, or floss.
